I took out what I assume are the 6 cyl engine towers out to replace with V-8 towers ,the 6 cyl. were welded in , I got the towers in (motor still in)and am having a hard time lining up the back drvs bolt and thinking the z bar is holding me up allso noticed the cylinder part from frame to eng is slightly bowed is this normal ? I did get both boltson top in on the pass side back one was hard but managed to get it in. The truck has a 350 in it with headers so its been a real pleasure to work on
