hello, i'm new to the site and i had a question.
we are taking the 400 that came out of my brother's 83 z28 and putting a 350 that came from a 80 z28. well, we got new motor mounts and we cannot get the old ones out. our camaro book doesnt say anything on getting them out either, so i was wondering if someone here knew how or knew a site that had the steps on it for us. thank you for your time.

there should be a nut inside the k-member, i think i've been told its 15mm. best thing to do is wrap tape on the back side of your wrench so when its loosened you dont lose the nut.

 

do you have any pictures of this? hate to ask...
thank you for your help

 

I don't have any pictures, but I'll try to explain.

On each side there are three bolts, the nuts are 5/8. I think the bolt head is 9/16" not sure on that.

I bought a little LED flashlight to stick up inside the Kmember. This helps A LOT!

Then I just got the nuts out using a standard 5/8 wrench on the nut. A socket on the top clamp. After letting some nuts off, or what ever pentrating lube sit for about 5 mins. I got to work. The passenger is easier than the driver side. I got the wrench cleanly around about 4 of the 6. I had to get creative for the others.

Putting them back on I used electrical tape to wrap around the nut. Electrical tape worked well because of its "give" . I also used a dab of grease to stick the washer to the nut. I got good at doing them as I did three sets in a day. Just wear glasses as there is always so much rust and junk in the k member.
