Home made engine support for motor mounts?

Folks,

I know I need motor mounts and want to do them myself and have read many diys on it. They all seem to say, push the engine up from oil pan (with wood block on it)...but I know that my dealer uses a brace to hold engine, I'm thinking (haven't seen it), that it goes between strut mounts like an front brace and it mounted on engine from the engine support hook in front. Then, they drop the front (subframe I think--'he' said four bolts drop something to get to mounts...I'm thinking maybe the whole axle drops?)

First, is that understanding correct so far?

I'm concerned about pushing up the engine and messing things up...like with my new trans. mounts, and, you know, all the hoses/wires, etc.

Given that, I've been thinking about the possibility of making an engine support brace out of something like a 2x6 or maybe two 2x4 sistered together...with some way of locking into shock mounts and a monster bolt gong through to bracket.

Totally crazy idea? You now what part I'd need to drop...and then what would drop on me if I go through with this...and finally, I'm thinking that whatever bolts I'm removing would be one-time use only...technically. Should I absolutely replace with new bolts...or thread lock enough? Would I need to support whatever would otherwise drop on me (of course) and if so, how?

Sorry...need my next diy and can't avoid being ocd about it!

Doug
