Driveshaft Lengths

[texasdave]

I'm trying to confirm the correct length of the driveshaft in a T/A with an automatic.  Is it 45.79 inches?  I have looked at various sources and keep getting different lengths!  The shop manual doesn't list a 340.  A chart I found on line lists a different length, etc.  It looks like the Parts Manual lists part# 2996142 with a length of 45.79 inches.  Could I please get a verification before I buy another one!!
Thanks!

45.60 is what I have listed close enough

The difference depends on the u-joint. 7260 - 45.79"    7290 - 45.60"

Thanks for the replies!  Now I'm ready to go to the driveshaft shop.

Are they the same size for a 4 speed?

Yes, 727 auto and A833 four speed would share the same length driveshaft.
