Add your abody driveshaft length for quick reference

To make this easier to figure out. The 3spd/904 use the same slip & the 4 spd/727 use the same yoke. The info you need when figuring lengths or swapability is,wheel base,what transmission & what rear end. The 4 spd,3spd & 904 are all about the same length from bell housing @block to end of tail shaft. The shaft is measured from center of joint to center of joint. The engine size doesn't matter because the trans mounts in one place & is factory set via the cross member.
