gmpartsdirect.com had the 24502456 PROM available last year for $66.63, but when I checked today it says not available. Guess I should have gotten it last year. I believe with the '86 ECM all you need is the PROM, but I can't say that for sure.
I remember seeing that reference in the mag, but don't have it in front of me (unless it is the Nov '06 issue, and I missed it as I went through it real quick here).
