Cab Mounts

[Ken B]

Rubber lasted 39 years....originally.
Figure it rode hard the last 20yrs..new rubber will feel much improved

I ordered poly from summit. Summit is always quick to me and has great customer service.
I have no complaints with poly bushings.
rubber may have lasted 20 years but poly will last your lifetime. Just depends if you wanna do it again.

 

[Ken B]

Understand your logic.
55 years old doing a frame off solo....this will last my lifetime or at least my time wrenching

So does anyone know if the 81-83 is a different height than 84-87?

I live in the Charlotte NC area. I get my big parts from NPD even thou they have everything LMC and Brothers have. I love not having to pay big shipping charges.

 

[Ken B]

I didnt know they were in Charlotte, got family there, was just there for new years. I will keep that in mind.
Good Info!

Can anyone guess what could be "different" between the mounts for a 1983 K20 and a 1984 K20? Both have the same number of pieces.....cannot imagine what is so different they need a different PN.

Based on the LMC catalog, the poly cab mount kits are the same across years, but once you go to the full kit that includes the radiator core support and bed it becomes a different parts number. Since beds are identical between years, there must be some difference in the core support mounts.

I went to energy suspension for my cab bushings.

I did the same with the 1981 metal onto a 1980 frame.

 

[Doppleganger]

I found that the difference between 73-80 and 81-87 are the shape of the bushings.

Some rubber 'kits' are the same PN from 81-87, so if you replaced them all, I cant see what the difference is. I'll have a set of 83's to look at shortly and compare them to the 85's I have.
