I actually wasn't sure how the other kits were done. This way I figured it would be stronger with bolts and nuts rather than threading the aluminum plate.
It would be a pain, But I think I could live with the last option mentioned: cut plate so it clears frame horn bolts, drill and countersink holes for bottom engine bolts. THen, when mounting, bolt the top two in, remove the tranny mounts with a jack under the engine still, insert the bottom engine bolts, then put the mounts back in and I'll be set!
Unless, of course there are any other ideas/suggestions?
