Slick 60's

Since I am putting in a 460 and C-6 from a 77 that has a long tailshaft I want to go to a one piece driveshaft,I am going to look at the 73 to 79s in the local yards that have the one piece shaft with a C-6 and do my 66 F250 and the 73 to 79 F100s to 250s share the same wheelbase so the shaft will go right in without any modifications.

Jeff,

I believe the '73-'79 wheelbase is 6 inches longer than the '66 F-250.

The local drive shaft company can fix that easily. Jeff

Yes, the 73-79 is longer but it may not help you even if it has a slip yoke trans as it still may be a two piece shaft on the 73-79. If you need one I have one from a 78 F250 sitting here. It is a slip yoke trans and a two piece shaft. I have not had the heart to toss it but I can't use it either. I was kind of hoping the rear shaft would be long enough for my Unibody shortbed after I do the engine swap. We'll see I guess. Some of teh long beds are one piece but none that I ever was lucky enough to find! Hawkrod

I had two 78 half tons with C-6s that had the one piece shaft and a 77 half ton that also had a one piece shaft but it had a C-4. Jeff
