New headers, new headaches - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I've been struggling trying to get the new motor mounts in, maybe somebody has some tips that can help me out?

The passenger side of the engine is done, everything is bolted in place, but the driver side is giving me a hard time.
-There are three bolts that hold the mount to the block, I got the top two bolts in, but I can't get a wrench or socket around the bottom bolt. The perch gets in the way and I can't get any tools in the small gap to start tightening the bolt.
-There is one bolt that holds the mount to the perch, and I can't get the hole to line up so I can thread the bolt in.

At the moment, it seems like it would be easier to remove the perch from the frame, bolt the perch to the block/engine mount, then try to align the holes on the perch/frame and bolt that back in. It doesn't help that I'm doing this work alone in my driveway, it's pretty difficult to nudge the engine around from underneath the truck to try and get the holes to line up.

Any suggestions?

Loosen the perch...the holes are elongated. I had the same issue when I changed mine to the poly mounts. Loosen both sides. It just take some finess, patients and a few choice words. I drove it awhile with the drivers side unbolted for a period thinking it would settle....not. Just had to keep at it. Even loosened the tranny mount.

That's an idea that hadn't crossed my mind. I was worried that once I removed the bolts holding the perches down I would have the same trouble getting them to line up. You loosened the perches on both sides? I'll give that a try. A few choice words (and some pushing and shoving) is what finally got the passenger side mount to line up perfectly
