Old GMC transmission question

[landman]

I am currently putting together what I hope will be a reasonable representation of a GMC 702 to put in a hopefully equally reasonable representation of the truck pictured below. These trucks, or at least the ones I knew had a 5/4 transmission set up giving 20 forward speeds. I believe the 4 speed was used to split the ratios of the 5 speed. What do you guys suggest I use for this? Or is that going to have to be scratch built too? I don't remember seeing those in the various after market suppliers sites.

The AMT KW W9 kits have a 5 & 4. If you need the aux send me a PM, I may have one.

Thanks Terry, I found an old thread that says the W-900 and T-600 kits have them. Would this be the one?

I also found the 5/4 = engine combo on eBay but the guy wants $35 for shipping only. I think I can get the model above plus shipping for less.

No, that's a Revell kit, completely different. You want the old AMT W925, Alaskan Hauler or T600.

Reached a mutually agreeable shipping agreement on the eBay item.

I think Dave at AITM has them.

Thanks for the offer Robert. My 702 is almost done. I have a WIP thread in big rigs. I'd like you to check it out.
