Driveshaft shortening question

Glad I found this cause " No, I don't". I'll be going 7.25 to 8.75 and figured to shorten driveshaft the difference between axle center to u-joint center of the two. Are you doing the same 1BD71 ?
2 1/4 inches Barge and you are good. Just did it (as long as the trnny stays the same).
