Front Drive Shaft Length - The 1947 - Present Chevrolet & GMC Truck Message Board Network

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

I know that the Corp 10 center diff is about 1 inch off center (left or right) than a Dana44. I bet the pinion is different too, I know the corp 10 has more "gussets" on the pinion area....

Mike,
Thanks for the reply. I've determined that the length issue was due to the rods running to the mounts. I didn't have the brackets that bolt up to the block. I was attaching them to the mount itself. I've got a scrap 454 bare block and mounted it into position and relocated the rear cross member and magically the driveshaft fit like a glove. Glad I didn't jump the gun and cut the shaft. I'll need to make the rod brackets. Thanks again, Tom
