Radiator support bushings

[Agent915]

Hey guys,

I'm about to order a body mount and bushing kit. My question is this...my chassis is a '69 GMC, the front clip is a '68 Chevy. Do I need to purchase a kit for the '67-'68, or the '69-'72 truck? Seems like I remember reading a post on here about the core support mounting points for the '67-'68 were "below" the top of the frame rail and the '69-'72 were level with the top of the frame rails. Any input would be greatly appreciated!

My 68 is flush with the top of the frame, (the core support stand) making them the thinner set of bushings.

I believe the later ones are lower than the frame rail.

Here's a link to the previous thread you mentioned in post #1.

Does anybody know how tall the mounts between the core support and the frame mount brackets are supposed to be for the 67-68? Mine were so rotten they are worthless to measure.

On my 67 I opened up the hole size in the core support brackets on the frame to the larger diameter that the 69-72 C10's used so I could use the polyurethane mounts. I just haven't gotten the cab back on yet so I can align the front clip & see how things line up.

I will machine the poly core support bushings down in height to match the correct dimension for a 67-68 if needed so my front clip fits properly.
