What A SURPRISE

[native-born-texan]

I have the 351 and C6 in the truck, no problem until I tried to put in the drive shaft and it is about 2 inchs too long. I went to the junk yard and nothing worked so I guess I have to have it cut, I wonder why it does not fit.

I did find a nearly new copper radiator to replace the alum. one and my speedo cable is too short

Are you trying to piece something together, or was this all off the same truck?

I have a 1985 150 XLT stepside with a 300 and t18 four speed, I bought a 1987 f250 with a 351W and a C6 that runs really well .I put the 351W in the 1985 with the C6 and every thing fitted up except for the drive shaft. The T18 had a long tail shaft so I just assumed the drive shaft would fit. I found a 1985 in the junk yard with the short bed but the drive shaft was 7 inchs shorter than mine. maybe the stepside bed is a shaft of its own. I will have it cut to length.

The driveshaft lengths will be different between an auto and a standard trans. Also between a regular cab and extended cab, etc. You would have to measure and custom cut unless you swapped from an identical truck, taking the trans and driveshaft.

I think another key factor here is 150 vs 250. The housings are different on the rear axle, and that could be where the issue is coming from.
