It's for the low rider look unless the previous owner was really short and wanted to lower the seat for easier entry (pcspeak

You just need to get the correct U-Bolts, chuck the blocks and I doubt anything was done to alter the driveshaft angle. Usually you only worry about the pinion angle is when you raise up on a truck and the axle is mounted under the springs. Some blocks have a compensating angle to tilt the pinion up, but on very large lifts you have to do serious work to the driveshaft to keep it from eating u-joints so they go with straight blocks.
I sure you will have to crank up the torsion bars too.
BTW Nice acquisition! Is the paint & shine as delivered or have you sent it to the buff-shop already?
