Are drive shafts for 73-79 short-bed F-100's the same size as 67-72 short-bed F-100's? I want to put a 351M with a C-6 in a '67, and want to just get a stock shaft from somewere instead of getting a custom one made. I also want to put a 302 with a C-6 in the same type truck, what stock drive shafts will work with this one? Both trucks have 9" rearends.

Thanks a bunch,

 

73-79 has 2" longer wheelbase than 67-72. engine size won't change driveshaft lengh any 67-72 with same wheelbase and c6/9" rearend should work. a salvage yard will have a Hollander interchange manual which will tell what lengh you need.

 

Thanks Carter,
I guess a 67-72 FE-block truck with a C-6 is what I should be looking for.
