longhorn low control arm question

[Steven R]

I have a 71 longhorn 3/4 ton lower control arm the is missing the bump stop bracket on the driver side. I have a option to get a lower control from a 3/4 ton roller frame that still has the bump stop bracket and rubber.

are these lower control arms the same 3/4 ton longhorn vrs reg 3/4 ton truck?

I am assuming they are but the frame is a 30 min drive away and I dont have pics of it to compare to two.

the pic below is of the passenger side showing the bump stop bracket and rubber that I am talking about, I might be calling it the wrong name...
