Schweet! I will forward them on and see what we can get. I am hoping this guy can come through as I have not dealt with him before. My source passed away from a bicycling accident so I approached another person I knew worked at Ford and he gave me this guy. Why they just don't post this stuff that is over 20 years old beats the out of me.

Well my guy struck out, here is what he had to say:

[COLOR="blue"]"Well I've run into dead ends.... The numbers you gave me are actually service numbers which are different than the engineering numbers which should be stamped on the parts. However was able to cross them back to engineering numbers and got:
E5SZ-5025-A = E5SC 5025 CG
E7SZ-5025-A = E7SC 5025 AF
But unfortunately I couldn't find any usage information or prints in our system. Guessing they are too old and now fall outside our retention window.

My thoughts on your question are that the k-members should bolt in place of one another, even the mustang k-members should bolt to the t-bird chassis. The difference you'll most likely see is in the location of the lower control arm mounting points do to differences in track, ride height, anti-dive, etc. It's not uncommon for those points to shift slightly over the years with everything else remaining unchanged.

I replied back and thanked him for looking. I guess it up to the masses to get out there and measure the stock units up. I will see if I can located any stock k-members here locally on my off days and see if I can get some measurements now that it is warming up.

Some general info grabbed from a Mustang forum.

As for factory K members, if your R&P is still utilizing the original(to your year) R&P bushings it would be best to stick with the '78-9/'84 K member.
Also '78-'80 K members the rear inner bolts are closer together than on the later 81-04 cars, which can be rectified to use the later and lighter K members. So.
'78-'80 direct bolt in.
'81-'9/84 require rear inner bolt location change to fit.(mod car not K)
10/84-'88 same inner bolt location mod and use a different R&P sleeved bolt.
'89-'93 I4 Ks are the same as 10/84-'88 Ks
'89-'93 V8 Ks have a 1" wider track width. These can be identified by the welded in upper spring mount vs the stamped hole with triangles.
