Shorten driveshaft?

Your going to have to pay for the driveshaft to be shortened twice. Once for the 360/727 and once after you blow the 7 1/4 into a billion little pieces then install a 8 1/4 or 8 3/4.
well crap,if a sbp A body 8 3/4 were a little easier to find and not so damn expensive to get(ive seen people sell them on here for over $700),I would have one already,lol.But when I DO decide to tear up the 7 1/4 ,ill be sure to take pictures of the carnage.lol Besides,I plan on driving it as normal as can.Im sure the 7 1/4 will not tear up just by cruising it.Its not going to be drag car.
