1966 GMC 305 V6 Motor Mount - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Driver's side mount completely separated.
Mounts not easy to source.
I have a 67 Mustang 200 I6 mount and it looks like a good match. I'll need to weld a 1/4" bar stock on it to obtain proper height and bolt spacing.
The ford mount only has one lower stud.
I won't have to drill GMC bracket because it has 3 holes.

Wonder what others use for mount?

Yeah, you pretty much won't find a source for those V6 mounts. The only option for keeping it original is to send your mount to somewhere like Steele Rubber and have them re-vulcanize it for you.

But good call on that F*rd mount. Looks close enough for government work. Let us know how it turns out.

Didn't mean to drop the F bomb

I plan to install one mount before drilling holes in welded on 1/4" flat bar.
Drop in engine. Bolt up finished mount.
Mark holes in other mount. Drill holes.
Hopefully that will assure mounts are under normal stress.

The other one; I've not tested this out but it does use the interlocking plate.

Does it actually fit unmodified?
4" bolt pattern, similar height and correct stud orientation?

Thanks!

**MusicMan70** · 04-06-2013, 12:51 AM

Rufton; Got that info from the 6066 GMC site. May be worth the time to take your old one down to NAPA and compare for that price.

**62 Longbed** · 04-06-2013, 10:53 AM

I'm not sure , but I was told that this number might still be good
from GM 2391949

**MusicMan70** · 04-06-2013, 11:14 AM

62Longbed, that number is correct but I don't think they are available. These are a lucky ebay purchase.

As Corts60 stated earlier, you'd have to send the old ones out to Steel Rubber to be rebuilt.

I will definitely give those mounts a try.
I'll break out the welder only if they don't fit right.
Thanks again

Thanks. I crossed those to Anchor 2337 because Napa kinda far.
They fit perfect.
Be aware the threads are metric.

Rufton, Thanks for posting the follow-up verification, Part number crossover and photos as well. That mounts looks pretty solid!
The original GMC mounts I posted are a very hard rubber, those must be as well. The price is nice.
Your V-6 looks great and you have the Spin-on filter as well.
