I've got this unknown SMEC that I found on the shelf. I thought it was from an '89 Shelby Daytona, but it seems that's another one on another shelf. Yes, I have too much crap.
Anyway, the only numbers I can find are on a badly faded silver tag on the top: 5235101 3418/2210
The way I determined the other one is the Shelby is it gave me code 23 on a 2.5 auto car that I'm still trying to get running; this particular unit did not.
Do these numbers help?
Thanks in advance
