been using similar technique for several years on a lot of V8 s-10 conversions and such. what I do different is use fishing line instead of the coat hanger, I use a push-on lock washer on the bolt before adding the motor mount. so the bolts stay in place regardless of the motor mounts. With the lock washer on the underside and the push-on lock washer sandwiched between the frame and motor mount you wont need a lock washer on the top. I DO like your zip-tie method though, Ive been holding it with needle nose pliers until i get the push-on lock washer started.

I like the idea of the push lock to hold it, if your talking about those real thin metal ones like they use in late model bumpers. Either way, sure beats drilling holes, dropping control arms, and losing sockets! Thanks for the feedback!

Gotta say I got 80 firebird, one side has no hole so I tried your trick, 10 min later I was done, million thank yous for this tip,I've been at this for months, amazing

[@shumanatorsgarage8921]

Glad it helped! Thanks for the feedback!

Has anyone ran the clamshell frame mount and fabricated the engine mount for a olds and whats the location of the frame mount

[@photosbuychris]

your missing the zerk fitting on your tie rod

[@shumanatorsgarage8921]

You're right! Has one now, thanks.

[@CodyDixieOwen]

Tried this today on my 87 caprice motor mounts worked great thank you for the helpful video 👍

[@shumanatorsgarage8921]

Thats great! Thanks for the feedback!

[@JamesAnderberg]

Another method is to spot-weld a hanger or brazing rod to the tip of the bolt and insert the hanger/rod from the back side. Slip the nut down the hanger/rod , once threaded onto the bolt nip the hanger/rod off. Easy Peasy.

Dumb question. So I’m good on a 95’ z28? With a Lt

[@shumanatorsgarage8921]

Cant say for sure but looks similar.

@@shumanatorsgarage8921 definitely fits doin em now thank uuuu the vid helped

[@GingeredRage]

This was a huge help on my GMC OBS truck. Thank you guys.

[@GingeredRage]

I suffered through putting the nuts on the inside of the frame when I realized I had installed the motor mounts with the tabs up on the outside instead of the inside. Original install was an hour or more with 15 trips to the toolbox for extensions. Your way took me 15 minutes and I was able to do it sitting.

[@shumanatorsgarage8921]

@@GingeredRage Oh bummer. I went through that about 20 years ago with my El Camino. This works way better! Glad it helped you out, the second time...thanks for the feedback!

[@mikegillam1000]

I wish I'd have watched this video the first time I did this! It was a frustrating two person job last time I did it. This looks like it should simplify things!

[@shumanatorsgarage8921]

Thanks for the feedback!

[@Kurnacopia]

Excellent video guys! I'm about to do this on a 78 Chevy.....I will be sure to watch again before the install.

[@shumanatorsgarage8921]

Thanks! And good luck! Take your time with it.

[@CameronZ28]

Everybody else is like "Just drill a hole in the side of the frame" but I don't want to do that, and this is genius.

[@shumanatorsgarage8921]

Thanks for the feedback!

[@christopherohara9421]

Some people drill a small hole in the side of the frame

[@edwardguzman6011]

Nice trick gona do it

[@Gaspumpduke]

So do I still have to remove the v6 k member or can I just put these in for a v8 swap??

[@shumanatorsgarage8921]

Sorry I do not know the answer to that offhand. You will have to do some research on that.

[@cj8172]

Great idea guys, except my engine is still in the truck. I'm not looking forward to this job, it's going to be so much fun. 😅

[@shumanatorsgarage8921]

Oh man, good luck with it!

[@ricardosanchez-op3ke]

Where can i find some strong bolta for those mounts and also i need the long one that goes through the mount and clamshell

[@shumanatorsgarage8921]

I got grade 8 bolts from the hardware store, had to go to a couple stores to get them all. The long bolts I think you can get from the autoparts store in the help area by Dorman or online

[@ricardosanchez-op3ke]

@@shumanatorsgarage8921 hey thank you for the reply

[@mfultz403]

So you shaved the insert to fit ?

[@shumanatorsgarage8921]

Yes. The polyurethane had to be ground down to fit the clamshell in our situation for some reason.

[@mfultz403]
