M21 vs T10

Now the M21 needs a new case. I am told the T10 bolts up but is two inches longer in the tail section. Need a shorter driveshaft now if I want to use the T10 (which he says is tough and like new inside).



Used driveshaft and have it cut, or measure and try to find the correct size? anyone have suggestions?

thanks.

Time to get out your yard stick. I've never seen a T-10 that was a different length than a M20/21 (except for the odd Pontiac Muncies) so don't take anyones word for it. Otherwise, you'll cut your driveshaft three times and find that it's still too short.
