I have some new engine mounts that are very tight.  I could Dremel the rubber and make them fall in place.  Don't want to take away any rubber and they will slide into the engine bracket ears from the side.  

 

My question, can I put the engine mounts onto the brackets then lower the motor in taking special care not scar the threads on the mounts (they came with plastic sleeves over them, add some tape at the bottom).  Then I'd have to hit one hole per side where the perch is.  Has anybody done it this way?  Thanks for any replies.

I had the same problem a while ago.  If I remember right, I left the mounting bolts loose so the mount could "rooster" a little bit and allow the various bolts and studs and holes to align.  Once the engine weight was on them the rest was easy.

 

Edit - actually, I think that I had to use an awl to shift the mount over to get the bolts through the holes after the stud was in the hole.  They didn't drop in to place.

 

I think I did the same with my transmission mount.

I'll have shave some off. 8 (

Where's the u-shaped piece that keeps the engine from moving forward and backward?

#9 #9 #9 #9....

 

 

Edit - added a better picture.

You've taken hair off the top of my head with that.

I don't understand?

My bad. Didn't see the other post. I'll get them and see, I'd forgotten about ole #9.

240s must not use them. I don't see them and don't remember ever seeing them anywhere. My red ones in storage so no comparisons.

Wasn't sure which are you were working on.  Maybe you got a 280Z mount.  The parts manual shows two numbers, before and after 8/73.

 

Regardless, shaving some rubber won't hurt anything.  Just more work.
