Thanks for the numbers, I'll look into it!
On the
Classic Truck Parts site looks like
BR2706-R inner set and BR2716-R outer set are what I'd need.
Still expensive at about $340 for all 4 bearings, but I haven't looked anywhere else yet.
They are tapered roller, which is an improvement and I wasn't sure was even available.
Can't seem to find them listed anywhere else by those numbers, so either they are custom made for the truck parts place, or they go by another number in the real world??
