On Friday I took a quick tour of the local U-Pull-It and found a base model Shadow with a what I believe was a2.5 TBI. I took a quick look at the ID tag to see if it was anything I could use and saw the strangest thing. A A523 built in 1990 with a 3.85FD listed on it. I thought that the 523s523 came only with a 3.5 or 3.77 FD. Anyone else come across an oddball like this? Once I get the computer and such up &running I'll post a pic of the tag.
