Can somebody help with SPID label? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

75-K5 · 03-18-2004, 04:36 AM

Can anybody help with the digits marked with question marks? Also, could someone maybe explain what exactly the HD springs are? Does that mean the coils with overload? What is the oilbath something or other? And what is the ??cnt stabilizer? I just got curious and wondered exactly what options this beast came with when new. Thanks fellas!

Here's what it looks like to me:

CDEL?: CE2C934
503AA: LIGHT GREEN
060AF: AUXILIARY SPRINGS EC
PL80A: SM WHEEL CARRIER
F60RA: HD FRONT SPRING
G?0CA: HD REAR SPRING
N30CA: 327 CU IN V8 ENG

46???A: GREEN VINYL INTERIOR
4T6??A: HEAVY DUTY TAILGATE?
4K????: OILBATH ??? CLEANER?
4P???A: ??CNT STABILIZER
4M2??0: 4 SPD TRANSMISSION

I am not sure on the RPO's themselves, but:

4T6??A: HEAVY DUTY TAILGATE? = Heavy Duty Battery

4K????: OILBATH ??? CLEANER? = Oilbath Air Cleaner

4P???A: ??CNT STABILIZER = Front Stabilizer (sway bar)

hd front and rear springs are basically heavier duty springs than normal. that doesn't mean the truck has the overloads, jsut heavier springs. "060AF: AUXILIARY SPRINGS EC" is what indicates that you have overloads. Oh yeah, and the 4 speed is RPO M20, but that does not mean it is the car M20. Either an SM420 or SM465 4 speed truck tranny with creeper first gear. i am not really sure how an oil bath air cleaner works, but i am pretty sure they were ordered for dusty environments.

hope this helped

Ah, OK thanks. Yeah well the air cleaner is long gone since the original engine is long gone. And that's a big duh on my part as far as the front stabilizer and battery, I don't know why I wasn't seeing those correctly.

CDEL?: CE2C934 ==> It's acutally MODEL
503AA: LIGHT GREEN ==> actual code is 503
060AF: AUXILIARY SPRINGS EC ==> not a 0 in front. actual code is ==> G60
PL80A: SM WHEEL CARRIER
F60RA: HD FRONT SPRING ==> actual code is F60
G?0CA: HD REAR SPRING ==> G50 No 'overlaods'. Just a stronger spring.
N30CA: 327 CU IN V8 ENG actual code is L30 for a 327

46???A: GREEN VINYL INTERIOR ==> I can't find my list of interior codes
4T6??A: HEAVY DUTY TAILGATE? ==> T60
4K????: OILBATH ??? CLEANER? ==> K48
4P???A: ??CNT STABILIZER ==> It's not a P: F59
4M2??0: 4 SPD TRANSMISSION ==> M20

Six digit RPO codes have extra 'fluff' in them. The actual RPO code is just 3 digits. There has been debate and speculation why there area extra characters in the codes, but I don't think anyone knows for sure.
