it's simple on paper, took me a few hours I could do it again in one or twoQuote:

3)both mounts have a large long bolt going through them, remove these bolts once the pressure of the motor is off and jack the motor all the way out of the mounts.
4)replace the mounts. do NOT put the mounts on the motor, then lower the motor back in place, it WONT work; the mounts must be tightened to the body before the motor is dropped back on.
5) use a bar to wedge the motor back into the mounts and replace the long bolt on each side.
6) you are done:)
NOTE: if you have a 6 speed, replace the tranny mount too, it is much, much easier to replace than the motor mounts and will prevent wear on them too.
thanks..im going at it this week end ill keep u posted
REMOVE THE PEDESTALS with the mounts.............ask me how i know......do 1 side at a time......easy as pie
Without a doubt, best advice you can take! Take the pedestals out with the mounts but only do ONE SIDE AT A TIME. I made the mistake of taking both off and got one on in no time but fought for hours to get the second side to line up because the motor shifted.Quote:

I have to change mine and i bought the clamshell inserts and its says you have to drill out 5 rivits holding the halves together is that hard to do? im guessing you have to unbolt it from the frame and take it out
you can remove the pedastals or remove the alternator and ac pump to get the bolts out.....i actually removed it all cause i installed poly mounts and its hard to line up the holes with poly mounts....pedastals had to be removed.
so ill have to unbolt it from the motor and the frame and take the whole thing out do you have to do that on the driver side as well?Quote:

did you have to remove anything else in the process? also what brand? I'm looking to pick some up before I swap my headers in this weekendQuote:

Make sure you mark the two halves of the clamshell so you put them back together correctly. My mounts were so dryrotted that after splitting them the rubber fell out. Sjsingle1 has some great pics in his thread: http://www.ls1.com/forums/showthread.php?t=133419

I had a whale of a time trying to get the big long bolts back through. The motor had to be twisted some to get them to line up right. Rather than prying, I took a ratchet strap and hooked to a point on the motor and then to another point on the frame and just kept ratcheting unti I got them to slip right in. It sure made it easy to do it myself with just the two hands i had on me.
