AL WTB: 4 flu radiator lower mounts

[GMCNUT]

Hey guys - hoping one of you can help me find a set of the lower clamps bradded to the frame that support the larger 4 flu radiators a lot of the big block or A/C equipped 69-72 truck came with - would buy the two uppers as well if you incidentally have them too....please let me know. Need these very badly for a buddies' truck we are working on....Thank you

Not sure if you want to go this route or not but when I converted my '71 4x4 to a 4 core radiator I used two upper mounts and removed the "saddles" from them by drilling the spot welds. Then drilled a hole in each and used a Phillips self tapper screw with a low flat head to mount to the rad. support. Also had to notch the rad. support lip because the lower support is larger than what was stock using the 3 core mount.

If interested I have two pair of the upper mounts with rubber cushions. Can bead blast, prime and paint if wanted or just as they are. $40 for the pair plus shipping.

Thanks - I need to do some checking on what you say regarding the lower channel on the radiator support being wider - so you are saying 4 flu radiator equipped trucks have a totally different radiator support than 3 flu equipped trucks and you have to notch a 3 flu trucks' support to use a 4 flu radiator?

The factory 4 core radiator trucks have a relief in the area where the lower radiator brackets go due to their length. Not a big deal as you can notch the area but there is a difference. I think Gary was just letting you know so you wern't surprised if you tried to put them in and it seemed fishy.

I have full 8-pc sets of new metal brackets and rubber mounts: $60 with a complete stainless hardware set. Plus $10 S/H.

You beat me to the reply Mike, thanks for the explanation. The four core mount or saddle being a bit longer needs a small notch cut in the rearward (engine side) of the radiator support. The support has a small ridge of metal that interfers with the longer four core mount. Was not a big deal at all, a little air grinder work and if fit fine. I loose mounted the radiator to locate the mounting area, marked, drilled a couple holes and used the Phillips self tappers to mount. The upper mounts fit fine with the extra radiator width. Hope that helps.

Thanks to everybody for your posts and info - I called fellow long time member JQ-72 (you all know him I'm sure) to ask about the notching required etc and incidentally he was standing in a salvage yard looking over a 72 Highlander long box truck someone carried to crush and believe it or not, it happened to have these darn 4 core supports still on it - so he is grabbing them for me as we speak - just one of those lucky days I guess. Very much appreciate you guys jumping in so fast though - thank you
