DRIPTROIT 71

That looks Awesome!!

Thanks Trevor!! Brian, I’m out of town, but will get those measurements when I get back.

Great looking build! The colors really set it off!! I like the tandem look as well. Excellent work!

WOW!!! Incredible work!

Making a little progress.

This was one of the actual trucks and trailers bought and built for the movie. I am not sure that either got any actual screen time though. It is a genuine survivor though.

I have some more pictures of the surviving truck. In this picture it looks like the bottom of the front is rounded if you zoom in. This is the only picture that I have on my phone. I have more that might help at home if you need them.

The only difference between a 281 and a 351 is that a 281 is single drive and a 351 is tandem drive. The 281 used in the movie was an older model, notice the drip channel across the front. The newer cab in the added scenes doesn’t have that. The surviving Duel truck that Brad Wike has is a 281 but it has been converted to a tandem drive. I’m pretty sure that Brad’s truck originally had a Page and Page set up like the crashed Duel truck.

Looks great so far!

This one is being built on a shortened Super Boss Chassis. Power will be from a twin turbo 8v-92. The hood s from Spaulding. The quality is so so. I have had the Bobby Griffin version as well and both have issues with the grille fitting. The other issue is that it seems like there was so much mold release used that it is in the resin. I scrubbed the hood with Comet, sanded it very thoroughly with 400 sandpaper, scrubbed it once again with Comet very thoroughly, and still had trouble getting the paint to stick. Here is what I have so far.

Most of what I have seen have two chambers per wheel. The single chamber on one side of the axle and the dual chamber on the other side. We always called the dual chamber; "piggyback" chambers because of the heavy spring in them that actuated the park brake. You could pick some good looking piggyback chambers and do a test fit to see how they look. You may have to make a short mounting post. If you are wanting to upgrade to heavy duty, I would just convert to S-cam brakes. More reference pictures: This is a Loadstar single axle and it doesn't have piggybacks.

The piggy back or dual chamber that is in these pictures appear to be the same size as regular s-cam chambers. The ones that I have seen in person (from what I remember) are smaller and closer to the model style.

Thanks Gary!! Thanks Bob!! Thanks Seth! The grille, side emblems and engine came from Rookie Resin. The hood was found on Ebay. I made the rear window conversion myself.

Thanks for posting this! This is so sad! Prayers go out to the family! Gary was my first choice for many parts! He always delivered in a timely manner and his stuff was great!! He will be missed!!

I tried to put this quote in the post above. I don't know how it ended up down here.

The air brakes that you are describing are known as wedge air brakes. Some wedge systems only have one air chamber per wheel. I have not built any of the C-cab Ford kits, but all of the AMT kits with wedge brakes that I have built have two air chambers per wheel. Just like with S-cam style air brakes there are two types of air chambers. There is a single diaphragm (air simply applies the brakes) and the dual diaphragm (one air line applies the brakes, one air line releases the park brake which is engaged by a heavy spring). The single diaphragm is the smaller chamber and only has one air line going to the chamber. The dual diaphragm has two air lines going to the chamber. You will notice the slight difference in the kit parts. The ones that I have seen have the dual chambers mounted at the rear on the rear drive axle and at the front on the front drive axle. The single air line from the single diaphragm chamber comes over the axle next to the backing plate and ties into the air line on the dual chamber line. If you look closely, on the right rear wheel you can see the single air line come over and tie into the line on the dual air chamber. This one is harder to see, but you can barely make it out on the left rear. This one you can barely make it out on the right rear.

I really thought that I had commented on this one! Excellent work! I like the older hood! Ice job on hinging everything! The lighting is excellent! I like the colors and the big tires! Excellent overall build!!

Thanks Brian! I have a mid 70s C60 cab. Would you rather me measure that? I also have a 9500 cab. Thanks Chris!!

Looks great! I like this combo! I especially like the daycab!!

Thanks Mike! I appreciate getting to meet you and picking both the cab and the bed from you. Thanks Warren!! Thanks Ken!! Thanks Dan!! Thanks Victor!! I was going for the barn find look on the truck. Thanks Jim!! Thanks Dave!! Thanks Alex!! I didn’t take any pictures of the engine. I got the oil pan measurement from the real thing. I then took an Italeri Cummins and cut it down to match those measurements. I chose that engine because of the basic shape and I had one junk. The oil filter and starter were very close to the right place when finished. It can only be seen from the under side as I made inner fenders. I will try to get some under shots later. Thanks Scott!! Thanks Lucas!! Thanks Philippe!! Thanks Gerald!! Thanks Doug!! Thanks Carl!! Thanks Rick!! Thanks Mario!!

Thanks so much for the tip!! This was extremely helpful!!

Thanks Carl!! Thanks for all of the comments guys! This one is now “Under Glass.”

I picked this bed and cab up from Mikemodeler, thanks again! This is the best resin Topkick that I have seen. It came complete with battery boxes and tanks. I used the new release of the old Ertl 4300 for the chassis. I cut down an Italeri Cummins to represent a 3116 Cat, although the hood doesn’t open. The 1 ton GMC was built specifically for this rollback project.

Thanks guys!! Thanks Joe! I’m not sure who manufactured this cab, but I believe it to be the nicest one that I have seen. Mike had one from P&P as well, and this one looked much nicer to me. Thanks Rick! I picked up the bed from Mikemodeler. They are available on Ebay from bcs-trading though. The deck and cylinders seem to be styrene. The headache rack, side rails, frame, slide/tilt assembly and wheel lift seem to be made from some type of 3d printing process. I’m not familiar with 3d printing processes, but this almost looks as if it was printed with plastic string. It builds up pretty nice though. The wheel lift didn’t have a cylinder so I made one. Bcs-trading offers a roll off body that I may have to check in to. They also offer a smaller roll back bed.

Thanks Mike! Thanks Carl!! I’m just about to the finish line on this one.
