There are conversion joints for most types of u-joints available. Meaning that you can use the smaller/larger wider/narrower driveshaft yoke with a dissimilar rear end yoke. I use two different mopar 8.75" pumpkins in my AMX, one with 3.90 gears for fun around town and one with 2.8? (not positive what the ratio is) when I want to go on a road trip. They are not the same series case and use two different u joint sizes, to make them both work I just swap in the conversion joint when mounting the smaller of the two. Same driveshaft two different sized rear end yokes. ~J -----Original Message----- From: amc-list-bounces@xxxxxxxxxxxx [mailto:amc-list-bounces@xxxxxxxxxxxx] On Behalf Of Swygert, Francis G MSgt 436 CES/CECM Sent: Friday, March 02, 2007 8:50 AM To: amc-list@xxxxxxxxxxxx Subject: Re: [Amc-list] Driveshaft swap was Re: So AFrican Rogue Make that 106" wheelbase 64-69 Americans. Won't work with an AMC20 because the U-joint has larger diameter caps (joint is bigger). I'm reasonably sure the Pinto wagon has a longer wheelbase than the hatchback. Not 100%, but... ------------------------- Date: Thursday, March 1, 2007 03:33 PM From: Wrambler242@xxxxxxxxxxx If you have a 72 up AMC 232-242-258 six with a T-5 transmission and an AMC15 rear axle in an American sedan, yes, a 77 Pinto wagon driveshaft is a bolt in! I'm using a true 82 Spirit T-5, it's overall length is the same as a Ford T-5. So barring unforeseen differences car-car this "should" be a bolt in to all American bodies that share the two door sedan wheel base. I'm not sure what the AMC-20 rear axle would do. If it's pinion is longer or farther forward I do not think it will work as it is a "tight" fit in my combination. Take a tape measure to be sure, though it would still be a good starter shaft to have cut if needed. The best part is the Pinto shares u-joint sizes with the American and is larger in diameter to boot! I found this by taking a tape measure into a Yard and measuring shaft lengths till I cam across this on. It was from a 77 Pinto wagon with a 4 cyl auto to be exact. IIRC even the yoke will fit in the Ford version of the T-5! It does not fit in the AMC T-5 as it uses the Chrysler 904 spline. :[ Mine cost me $25! :] Sure beat having one cut or built! _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
