Thank you for the help. BCD is 3.75" all around. Found the code on the shock tower of AM 83 27--so early 1983 model. There is a bung in the back where you mentioned, if by bung, you mean welded nut on the interior frame. The steering rack is a Caterham. I'll get pics of the diff and steering rack once the car is on stands; I'm heading out of town for a couple of days and will do it when I get back.

So, I just bought my first 7 as a non-runner that was in my friend's shop. Right now, pretty much only some word of mouth about the car from shop owner, but no documentation, I can't even find the Caterham plaque. Anything you can tell from the pics, or other pics that maybe I should take or things I should look for would be very helpful. Also, is there anywhere I could find a build manual? The wiring looks like it was done by a 3rd grader, so first priority is rewire and replace ECU with a Megasquirt. What I can tell so far: Raceline engine, shop owner said it's a 250hp version Pretty sure it's a live axle. Buddy thinks its a Ford 9" but not 100% sure. Otherwise, any insights or observations are welcomed! It's my first Caterham, coming from Miatas. My hope is to have it out for HPDE this Spring and we'll see where it goes from there. Thanks! Matt.
