I have a 53F100 that I am putting a 302 with a C6 tranny and have a stock Dana rear end with a 3.92 ratio. The truck did not have a motor, tranny or driveshaft when I bought it. I have access to a driveshaft out of a 1987 F150 and was wondering if anyone knows if this shaft would fit. I know it may have to be shortened but I am mainly concerned about the yokes. It will fit on the tranny side because I am useing the C6 tranny out of the F150 but will it fit the rear end side? Thanks for any help someone may be able to give me.

They make u-joints that will adapt things over. Take the driveshaft with the u-joint you have to your local Napa store. Get them to look up and get the u-joint for the original rear yoke on the old truck. If they have the bearing cup diameters, and the width, they should have a u-joint that will fit. That's how I did mine on my 53. I also installed a slip yoke out of a early bronco into my 80 4x4 by using a u-joint that adapted it over.

 

I just got two "conversion" U joints at my local drive shaft shop. I found out that ALL Ford F-1 - F100 48-66 had all the same u joints originally. The cap dia is 1.063"-1.064" and a 3 7/32" yolk width. These numbers plus the measurments for the driveshaft end and you'll be in business. The u joints were cheaper at the driveshaft shop then at the parts store, and the parts store had to special order them.Good luck, Rich.

 

Thanks a million Franklin2 and Cobraguy, that helps me greatly!

if ya gt a wreckin yard that will letcha walk around just take a measuring tape with ya and checkout every driveshaft ya come across that looks close.....actually some yards have a pile of shafts ya can paw thru. i just completed a s/b chevy conversion in my 58 merc 100 & ended up that a l/b reg cab s-15 shaft was exactly right(including the $10 price tag), just hadta buy the adapter universal for one end.....lot more cheaper & y'know the balance should be there in the driveshaft if it is factory made.

A '76 Granada shaft was just right lengthwise for a 302/AOD in a '50 F1. It had the correct joint at the rear and used the same yoke as the AOD. I don't know about C6 splines, but there is probably a yoke that will work without trick joints. I would stay away from trick joints, you can't always find them in the middle of nowhere in the middle of the night........

 

The ones I needed where in stock at napa. They acted like it was no big deal.
