Front Drive Shaft Length

[TLoz]

Hi everyone,
I dropped in my 400 turbo with a 203 bolted up to it. Hooked up the tranny insp cover rods up to the motor mounts. Went to install the front drive shaft and it is about 2 inches to long. The transmission, xfer case, driveshaft and frame came from GM together. The front diff is different. It was a Dana 44 and is now a corp 10". No change in the springs. Don't have them on backwards-the stabilizer bolted right up to the spring mount and the frame. Just wondering if the pinion length is different. I plan on taking the shaft over to a place here and getting it shortened. So, I guess the question is; are the Dana 44 and corp 10 different in the length from the spring perch to the pinion/driveshaft attach point. Thanks, Tom
