Radiator Support

I am attempting to resurrect a 76 j10. Not a restoration by any stretch, but a reliable driver. I need one of the radiator support brackets as my pass side has rusted to gone on the lower end. That's the part that the bushing supports for further ident. Any possible sources? I have the probable PN (J5455173) if that helps. It's a 258 T15 D20 with drum brakes, Talk about base! Any suggested alternate solutions also solicited. tnx

Also post this in the wanted section - some folks check in there more.

I got mine from a parts truck, so the junkyard is the only option I have experience with. Possibly most fsj support brackets could be made to work.

BTW, welcome to the forum!

On a completely unrelated note - were those drum brakes power? I just started looking for a source for an fsj power drum/drum master cylinder to go with the 77 j10 booster I have, so I know what to ask the parts guy for.
My rig started out as a 258/3spd/d20 too, and all manual drums. The drums are the only thing left but I'm keeping 'em.

Back on topic......

First post - welcome from Boston. Yep, disk brakes were first optional in 1974; standard front drums were eliminated for 1977. The stronger T-15 replaced the previous T-14 with the 258 in 1976, so you have that going for you.

Since you have a part number, you know that the V8 trucks and the 258 trucks have different core supports. The core support consists of three pieces, a splash panel on the bottom, the outer part that supports the grille, and the inner part that supports the radiator. These bolt together to make a assembly that spans between the fenders and rests on the front of the chassis.

This is shown clearly in the '74-80 factory parts book, which you can buy on CD-ROM for less than $25 from RockAuto. None of the three parts above matches the part number you give. Where did that number come from? Jeep did not use the "J" prefix in this era. I think that's an artifact of the Chrysler era, added to the existing Jeep part numbers at takeover. A legit part number from 1976 would be 5455173.

Anyway, I don't think a part number for this will help you. The bracket you want appears to be part of a larger assembly, and body parts are no longer available by part number on the aftermarket. Indeed, there are very few new body parts available for these vehicles today. Check BJ's - whatever new is on the market, they will have.

Suggest you go to car-part.com and look for a 6-cylinder J-truck or Wagoneer core support in your area, from around 1976. Unlikely, but maybe. I'd also suggest you take a picture of what you want and advertise with it in the WTB (want-to-buy) forum here and on other Jeep sites. There are also specialty junkyards that might have your part - see the forum for vendors.

Not sure what your bracket looks like, or how strong it needs to be, but can you fabricate one?

Maybe use aluminum, or if steel paint it, before install?

The original lasted this long, so sure the next one of the same material would last till the truck has reached expiration......which we hope is a loooonnngggg way off

Yes, mine are power drum brakes.

The PN came from a 1984 Mopar parts listing that I found. It looks like they listed the heavy support brackets separately. Also appears the brackets can be used either "narrow" for the I6 or "wide" for the bigger radiator as there are two positions for the support mount to the frame. My driver side has exactly the same piece completely intact. I may separate it from the thin sheet metal and have someone repair/duplicate it for the pass side
