help with "69 C20 rear shock mounts

[bowton]

I am doing a light restoration of a '69 C20 Custom Camper Special.

I am stuck on the rear shock replacement because I thought it would be easy

If someone could tell me what stock looks like I would really appreciate it since mine has been basterized through previous owners.

I bought some Gabriel OEM replacment shocks and need to figure out the proper way to mount them.

See attached pictures. The first picture is the right rear. It looks like someone welded a shock bolt to the bracket. The outside diameter of this is too large to fit within the Gabriel sleeve/bushing.

The second picture is the left (drivers side) rear. This looks like it might be factory but it is bent as well. Not really sure what I am looking at.

There are two holes in the bracket one forward and one aft. Which was used at the factory to mount shocks? Was the factory hardware? Bolted through one of these holes? If someone can suggest a remedy I would really appreciate it.

I have an angle grinder so If I have to cut off the welded one and grind the weld fillet out I have that capability.
