actually I don't even have the torsion set up. my truck was given the smaller of the two solid front axles available in '62. my shop manual supplement says that it was a new design for this year so I'm not sure much changed with this front end for a few years. From what I've read, I have the same frame as a half ton but with bigger leafs in the rear. Also, the front leafs are pretty large as well but it's a 125" wheelbase so that should be about right I think.
I guess I'll have to get out the tape measure and see the difference between the wheelbase widths. I take it I should be measuring the inside of the two tires and not the outside if I'm not able to get a hub to hub measurement?
I'll have to see which trans I have and if they had changed over a two year period. my truck is a '90 but the motor is from an '89 I guess. I'm not even sure if the trans is original to the truck or the other motor but I guess only so many transmissions will fit on the back end of that 2.5L four banger. anyone out there know the difference between the 4cyl trans and the one(s) used on the 2.8L or the 4.3L?? I'll buy one if I have to but it'd be a shame if I couldn't use the one I already have.
And I'm positive that g20 van has an efi badge on it... then again... badges are cheap and who knows if the original motor is in this van. I've got some research to do!
