Those could be more off…I’d think.I think the driver side needs it more than the passenger, but both are actually off about the same. I blame the LMC mounts. I may try switching to the GMT900 mounts if I can get them from the dealer still

I’m not so sure about that. I know people do this conversion on 400s as well as 800s. I’ve never seen anything bad about it.Those could be more off…I’d think.
If GMT900 mounts work, then GMT800 should, too? Those two generations seem to have a lot more in common than either with the GMT400.I think the driver side needs it more than the passenger, but both are actually off about the same.

Curious to hear how the body mounts work out. Which year/model did you select?I was able to get the body mounts for about $200 from my local dealer. I’m going to give them a try.
I didn’t use a specific year/model; I had part numbers from an old GM Truck Central post by Aloicious. His write up is good, installed these mounts in his ECSB GMT400. Thankfully I was able to source them directly from GM.Curious to hear how the body mounts work out. Which year/model did you select?

Don’t forget to post the dimensions on those, and I’ll post the OEM sizes. Hopefully, they are the same.I didn’t use a specific year/model; I had part numbers from an old GM Truck Central post by Aloicious. His write up is good, installed these mounts in his ECSB GMT400.

From his write up:
Here are the GM part numbers as well as the total quantity you’ll need to get again:
Upper Mount 25791031 - Qty 2
Lower Mount cushion 25791032 - Qty 2
Washer 15854745 - Qty 2
The upper mount however has been superseded by a different part number of 25994881…below is a picture of both part numbers, the mount on the left is the original P/N 25791031, the mount on the right is the newer P/N 25994881. You can see where the red arrows are pointing which shows the difference between the two. In this swap I used P/N 25994881 (the one on the right in the image) for both sides. I received 1 of the #25791031 mounts and found it difficult to find another one. Either part number should work though.
Of course. Should have them tomorrow.Don’t forget to post the dimensions on those, and I’ll post the OEM sizes. Hopefully, they are the same.
