I have a 1990 S13 in the shop that we are working on, we are trying to get the suspension sorted out but have hit a few brick walls and i could use a little help.

The Subframe has the Hicas setup, with the Whiteline Hicas delete installed.
I don't know what the subframe is from, if it's a 91+ S13, or from an R33, or even an S14.

I don't know what rear knuckles are on the car,

The car currently has 5 lug wheels on it,

Is there any easy way to determine what parts are installed on this by measuring something or something like that?

The owner was told that it had an R33 rear end, but i'm not sure if it is just the rear diff or the whole rear subframe/arms/knuckles, etc.

Any help you guys can give would be great!

Edit, the main problem that i have currently is the Hicas ball joints in the knuckles are bad, and they are different from S13 to S14 so i don't know what to get for it.
