Early solid thick one piece plate or later abbreviated caliper bracket with tin shield?

The latter. I have not taken anything apart yet but I assuming the two styles are not interchangeable?

The interchangeability may not span as far as 73-91. Certainly for a period of at least the late 70's-91, the axles otherwise have the same knuckle and spindle and thus, can use either style. I may have a later tin style shield, for one side. Useable and not rusted through, but I'm in the salt belt too.

Ah, glad to hear you know this, thank you! I have searched the Internet for hours trying to find information. I found the part numbers but then realized the same part number may point to the two different styles.

I got the axle from the local salvage yard; they set it on the ground and twisted up the shields. I did find a thick one and plan to use it if I can.

The axle ring gear is stamped 10 85 (1986 model year?) and I am still trying to figure out the axle stamping code to determine the year of the unit. Seems to be an extra character based in the code based on the information I found.

Thanks again for your help!

Ring gear stamped 10 85 is October 1985 for 1986 production. I'll dig out the caliper bracket/shield I have and image. There are lefts and rights.

I have three caliper bracket/rotor shields. Caliper mounts are good. Shields have rust through holes from road salt. They're available if you're in a pinch but I'm sure that there are cleaner out there.

I will pass on the rusted-through shields GonicGM but thanks. The information you shared was great though, it has helped.
