Well....I have a suggestion, but...you ain'ta gunna like it.....
LOL
But really....WHY solid mounts? On a street car, your prolly not gunna like them anyway, because you will feel every little vibration, the engine makes....you may wind up needed a mouth guard to keep yer teefers from chattering.
Why not go for some urethane mounts? They are way more "solid" than stock rubber mounts, but much more forgiving than the solid mounts. Just an opinion from someone who has used solid mounts in MANY cars back in the day....when comfort and civility had no place in one of my cars. Also, in certain instances, having solid mounts can wind up breaking the engine casting where the mounts bolt up, if the frame flexes a little too much.

Anyway...back to the original question....unless you plan on pulling the engine to get them in, the only advice I can offer is to loosen the trans mount bolts, jack the engine & trans up high enough to get the mounts loosely bolted to the engine, and then wriggle the whole shooting match around to get the mounts lined up, then drop it all back down a tad, and tighten the bolts holding the mounts to the engine. They are a pita to do, even when you have room to work with....they are not very forgiving of mis-alignment, so the engine/trans needs to be fairly level to get the mounts back down over the chassis brackets.

hth...and good luck!

my engine isnt "built" just basically stock.. one of the reasons I went with solid is the alignment of the eng. the motor mounts are on the block and one side is done but the sob wont line up, and that my issue.

I've had urethane and busted them easier than rubber (not in this car)

I'm with Joel on the poly mounts.  The installation and operation of my Energy Suspension mounts has been great so far.

Ive used the solid motor mounts back in my younger days with  dodge products. Back then I thought it was cool to have the vibrations so you could feel the engine lope. I thought about that when I did the 72 but decided the poly mounts would be good enough. The seem very solid and tight. I am happy with them. My engine doesnt lift or twist and I am far from stock. If you decide to stay with solid mounts you may have to loosen the trans at the back of the engine to get the right angle to drop down on them. Hopefully you dont have to separate the motor and trans but they should fit.
Best of luck.

I have the poly mounts also, they sure act like solid mounts, engine does not move. No vibration problems though.

On the other side of the coin, I have solid mounts in my 74. They came with the car when I bought it. Had the engine out and back in twice already and the only problem I encountered was making sure the mounts were on the correct side. It shouldn't make any difference but it does in my case. I bolted up the mounts after engine was secured to bellhousing with 4 speed still left bolted in. I suppose it is possible you ended up with misaligned mounts from the get go. As far as vibration....yes you do feel all the strange vibrations the engine makes but I personally like the fact that the car rocks at idle from the cam....just me sayin  Smile

I actually use a one solid and one poly on my big block cutlass kept breaking the drivers poly mount. big block has no problem shaking things up so i keep the poly mount on the passenger side since i know the car twists alot. 

I did the same in the vette because i liked the idea. I bolted up the poly side and had to use the prybar a little to get it in the other side. Then bolted the tranny up last.

It's all a matter of wiggling and pry bars. I'm with Joel - I would never go solid mounts. Even on a mild motor (who am I to talk   Wacko)  you'll get a lot of new vibration telegraphing through the frame.

Good luck with whichever route you decide - my recommendation would be the poly mounts...
