front drive shaft lengths?

[sope]

Anybody know what the length of different front driveshafts out of different GM combo's are? Really, I want to know what will fit in mine. I have a 465 / 208. The stock shaft is fine but I guess a little longer may work with 4 " lift springs.

I know the two I dealt with this year:

th350/205 compressed length is 25.5"
th350/208 compressed length is 32"

If I am thinking correctly, an auto trans and 208 would be a longer shaft than the 465/208 you have now, with the 700r4/208 combination being one of the longest.
