Im looking for a set of body mount bushings for a 78 K 20 truck
I need all three sets
I have The PST bushing set but i do not have any of the original hardware ( the insert sleeves ) which PST says are needed
Does anyone have a set or can anyone tell me if the two wheel drive and four-wheel drive are the same
There is a 78 blazer that's local but its 2 WD

Never heard of a 2WD Blazer. Sounds kinda suspicious.

Asking out of curiosity, what happened to the ones on the truck? It’s not like people are frequently changing those out.

They were produced until ‘82.
That’s crazy. I’ve only ever heard of their designation as K5, with K = 4WD. Never heard of C5. Must not have been very many of them.

Mounts are different between C10/20 and K10/20 pickups, Ks are larger.
I’d assume it was the same for the Blazer.
I was looking also, they are on back order most places but did find them at CJ Pony, they have truck parts.

They all carry the “K5” badge / designation until it was dropped completely around 88 or so.

Try LMC. Update, I checked, looks like they have what you're looking for.

Why can't you just buy some tubing and cut some sleeves.

I'm replacing my bushings soon because I recently noticed my bushings are shot/got. Found these but was not sure if this was a good set.
