fatdaddy- Did you see my post on the fact that it took me TEN hours to mount a 4 banger on a 29" Onex? No joke. Lack of experience, or lack of skill, I don't know
...but without having machined mounts, if you put the time in, you can still get it hella flat to the frame. That's the right way.
Metal to metal.

Words that have motivated me plenty of times.
