Looking for assistance identifying what conversion kit and calipers I have here (pictures below) as pulled the wheel off to discover that I had lost a caliper pin on one side and am looking for what replacement pin to pick up. Would also like to ID caliper type for rebuild purposes.

It appears to be the type sold by JT here:
Rear Disc Brake Kit for Toyota Land Cruiser FJ40 FJ55 FJ60 FJ62 FJ80 Conversion – JT Outfitters - https://www.jtoutfitters.com/product/rear-disc-brake-kit-for-toyota-land-cruiser-fj40-fj55-fj60-fj62-fj80-conversion/

Monte carlo calipers a safe assumption?

Thanks

They might be a Eldorado rear calipers. They were similar to Monte Carlo calipers except they have provisions for an ebrake. The gm pins are common and can be found at most auto parts stores. M/C calipers would work but have no e-brake.

When I had one go astray, I got a 'Doorman - HELP' replacement pin from the auto-parts store. The replacement pin was slightly oversized with a built in tap to cut larger threads into the backing plate. It also had a provision for a cotter pin to make doubly shure it wouldn't just walk away.

Here's what they looked like...
I CAN'T say if they'll be the right ones for YOUR application. I'd recommend bringing in an old pin when you go. Also check that the old pin fits tight so that you know if the threads are messed up or need to be re-tapped or a Heli-coil.

First post nailed it, thanks! Definitely eldorado calipers and the pins/bushings were an exact fit.

Great link, thank you. I do have problems with the e brake loosening. This truck has the dash-mounted "corkscrew" ebrake handle that has been fitted to actuate the rear disk brakes.

The threads, somehow, are OK. I may use light thread locker to keep this from happening again.

Local auto parts stores do not have any staff who know about parts. Without a VIN or year/make/model, you are on your own.

In ‘96 when I did my engine swap it was hard to find a parts jockey that knew anything about parts. Since then it’s gotten far worse. Now parts manufacturers have decided that parts don’t need to fit the specific year you carefully asked for.

It’s even worse if you try getting disc brake parts for a ‘74 Fj40 from the Toyota dealership. According to the vin I’ve got 4 drum brakes, a semi-floating rear axle, an F engine, etc., etc. Their mind would explode if I went tried to buy parts there.

Looks like an old TSM caliper bracket mount.
