I have an 89 Iroc. I tried to search this question, but the search is down.
Do your motor mounts have a Bolt and nut fastener? (mine do) If so, do you need to pull the lower control arm off to gain access?
I ordered some ARP mount bolts and they are just bolts. I am thinking I have the wrong part.
I am gonna be pissed if I have to take the lower control arms off again, since I did them when I did the busings and the eibach springs! Crap!
Thanks for any info,
Tucker

 

to do motor mount bolt you do not need to unbolt control arms. but remember you will need an engine hoist so that you can move the motor around to align the bolts

 

My engine bay is empty. I put the impact wrench on the motor mount bolts to replace them and realized that they have nuts buried under the crossmember.
I got under and saw ZERO clearance for 2 of the nuts.
I was thinking that someone had replaced the mounts and used the nut/bolt setup because the kit I ordered from ARP looked like they juat torque into the crossmember.

 

you can get to the bolts buy using using a 15mm universal socket. Some people have been able to bend a 15mm wrench to get the nuts.

It requires alot of time and luck. Took me about 5 hours.
