Need conversion u-joint for engine/tranny swap
Spent the weekend pulling the 360/manual out of my f100 and replacing it with a 460/c6. Engine and tranny are in with the exception of relocating the tranny crossmember mounting holes, didn't expect to but both sets are to far forward. Here's the problem, the drive shaft is set up for the manual/9". The shaft is to long, not an issue, I've cut down and re welded several while maintaining the proper balance but the manual slip yolk is to small for the c6 output shaft. I have the correct yolk but the u joints are different. What I need is a u joint to mate the new yolk to the old shaft. I haven't pulled the old joint out to mic it yet but thought someone may have already done the swap. I'll measure and post in the morning if need be. Not a joint expert but the c6 uses the same joint as several of my 4wd Fords, I belive a 1350 joint. I belive the existing joint is a 1330, not sure, smaller than I'm used to.
1976 f100 sb 2wd
Originally 360 with 3.03 manual
Now 460 with c6
9" rear

If you do need a 1330/1350 conversion joint, Summit has them.
Moog number is 448.

I used the chart in the link to figure out what my joints were.
My 205 tcase has 1330s
Rearend in highboy has 1330s
2wd auto rear driveshaft had 1330(don't know year)
1997 f350 front axle has 1330 BC(big cap)
Not sure when Ford used 1350 joints as all mine were 1330
U-Joint series identification

I have a brand new one I don't need......rather see it used than sit on a shelf. It's just been installed for mock up then I changed driveshafts.
