well the 6m block sits about 4 inches forward from the stock rolla mounting location, BUT the w58 bolted right in, and the 5speed front half shaft fitted right onto the rear half shaft of the corolla. it was a perfect fit.
if i landed the engine farther back, the drive shaft would have needed to be modified, and i would have to move the portioning valve for the front brakes. and all the lines... but as a down side of where it is...it currently is touching the brake master cylinder, and i need to fab up some bars to hold the motor from twisting from torque and tearing off the master brake cylinder
pics coming soon.
