8.5 swap: is my driveshaft too long?

I have a 68 chevelle with a th400 and an 8.2 rearend, i had the driveshaft made and it works good, there is alot of play in it tho, I am goin to swap my rearend for an 8.5. will my current driveshaft be too long? i heard that the difference is about an inch, if so i will be fine, except for the ujoint i think. Does anyone know forsure what the difference is between rearends and the driveshaft?

My 8.5" 10-bolt (out of a 2000 blazer) is 12" from axle centerline to the yoke centerline.

lucky lucky, those 8.5 10 bolts are hard to find in the S-10's. I gave up finding one for mine and got a ford 8.8

It took me a long time and many trips to look at "8.5inch" axles that were really 7.63" axles. The only thing that didn't bolt up on my 87 was the e-brake cables and the driveshaft needed to be shortened 1" (which is why I know how long the 8.5" is from yoke to axle centerline ).
