They have had a thread running about using aluminum driveshafts - has anyone run one in their y-block powered car or truck? If you were running a transplanted 8.8 rearend the Mustang parts would be a natural match-up. The aluminum part has a lot less rotating energy in it to vibrate and reduces the "unsprung" weight of the rear suspension. There are apparently chebbie pickup aluminum shafts around but they have a composite on the interior and can't be easily altered.

There was mention over there of using a shaft from Quartermaster - roundy track race car parts house - and getting a used part altered by them to fit a '32.
