Mr mopar Posted May 22, 2017 Posted May 22, 2017 Doug, probably because Johan's Road Runners while getting somewhat scarce, can still be found at relatively reasonable prices. AMT's take on this bugged me for years, and it's something I always wanted to tackle to see if it could be done. BTW, Revell's '67 Coronet suffers from the same malady. I have a fix in mind for that one too, but it'll be quite a while before I'll get time to take on that one. I'm glad I have three Johan 69 Roadrunners in my stash ,your a big help bill Thank you!
superbike-shaun Posted May 26, 2017 Posted May 26, 2017 Bill,a standing ovation to you for your bravado in taking on this somewhat of 1/2 assed iteration of a beautiful muscle car (and kicking its butt!) Also props for putting your seasoned experience out here where even the novice,builder can understand what is going on! Thank you Bill!
Mr mopar Posted July 15, 2017 Posted July 15, 2017 Ok I started to do the fix on AMT's 69'GTX and change it to a 69' Roadrunner ,one thing you must have is a 69' roadrunner Johan rear bumper because it has the peak in the meddle of the bumper , and cut out the rear panel of the AMT GTX and make the bend in the meddle , will have photos later of work.
MrObsessive Posted July 15, 2017 Author Posted July 15, 2017 Doug, you might not need to get a Johan bumper to correct the AMT body. One can make the "splits 'n' bends" in the AMT one to correct it. If you've got extras excellent! But not everyone does and sometimes just getting separate parts for those old Johan kits is like pulling teeth.I'm curious as to your take on how you fixed AMT's bad body. This is beating a dead horse, but why they keep missing the mark on body lines is frustrating to me, and in this day and age with CAD systems and all, they should be spot on.Shouldn't they??
Mr mopar Posted July 16, 2017 Posted July 16, 2017 Bill I followed your lead on this one ,I did everything you did. and I must say it dose look much better with the back fenders lifted up .

Be carefull. A 69 rear bumper has the 2 round backup lights in it, 1968 does not 1968
MrObsessive Posted July 17, 2017 Author Posted July 17, 2017 Keep in mind the AMT RR body was tooled up almost 30 years ago... Yes, I know..........but the problem persists. Johan had no such thing (CAD, and whatnot) in the '60's yet their bodies were spot on-----for the most part. And it ain't just AMT that's guilty of this.
Mr mopar Posted July 20, 2017 Posted July 20, 2017 Some progress on my AMT 69' Roadrunner .The Blue car is a Johan .
Mr mopar Posted July 20, 2017 Posted July 20, 2017 one thing I did notice was Johan left out the seam lines on the rear deck ,from the rear window to the trunk ,and Amt got it right .
Snake45 Posted July 20, 2017 Posted July 20, 2017 one thing I did notice was Johan left out the seam lines on the rear deck ,from the rear window to the trunk ,and Amt got it right . Those are easily scribed in. Thanks for bringing them to my attention--I might have missed them on my next JoHan RR build!
Mr mopar Posted August 6, 2017 Posted August 6, 2017 This is coming slowly but there is one thing you must use the Johan rear bumper because it is wider then the AMT bumper.
Peavus Posted January 31, 2018 Posted January 31, 2018 I have done the backdating of my 69 road runner to a 68. The trunk tail panel was cut from the amt body along with the tail light housings. One other thing is the side marker lights on the amt are recessed into the body. Those lights are supposed to mount flush on the body.
Bob Ellis Posted January 31, 2018 Posted January 31, 2018 I swapped the AMT trunk onto a Johan body. Also did it your way.
mikemopar70 Posted February 1, 2018 Posted February 1, 2018 I agree 100%, i planned to fix my Road-Runner this way comparing it with the Jo-Han... You did a prefect job correcting it!! Now the proportions are correct and the body looks like the real car!

You did a prefect job correcting it!! Now the proportions are correct and the body looks like the real car! Another thing that I did was fill the underhood scoop cutout in the 68 hood. I have found if I don’t it will leave a ghost cutout line after painting. I think the thinner plastic on the cutouts, has a different expansion rate than the thicker plastic surrounding the cutout on temperature changes. As the thicker plastic around the scoop cutout warms, it expands enough to push the thin plastic cutout line up. It’s doing the same on the other side of the cutout line. No matter how much sanding and paint the cutout line will always show on top. Anybody on the forum ever experienced this or is it just me?
