Half Shaft Mystery - Page 2 - ZR-1 Net Registry Forums

1990 #622 was the switch over from steel to aluminum. Maybe prior owner switched from steel to aluminum (some have done that for "weight savings" and looks (no rust)

my question is : is there a chance these alum. half shafts were intalled at the factory on such an early car, or have they been replaced? It seems very strange that they would be replaced with such low mileage. I found the following part numbers on stickers on the shafts: right side 14041925 - AR8??3, left side 14041925 - AR5033.

The part # is/was a "production" shaft used for very early C4's. It has "service/replacement" applications in early parts catalogs for '84 MY only. I would have guessed the AR5033 to be a date code and my thought would have been '85 33'd day of year. The AR8??3 though would seem to disprove that. It's I believe though very safe to assume they're "replacements" and not '90 MY production parts.

Here's a thought for you! The car left on a "test drive" with the "steel" and returned with the "aluminum"!! More difficult "swaps" have been accomplished!!

I appreciate everyone's input. The test drive/swap theory has got me thinking. So now my question is, are the aluminun half shafts I have now, that are from an early C-4, strong enough to stand a beating from a ZR-1? And if someone had an earlier C-4 with these aluminum shafts in it, would there be any reason for them to prefer the steel half shafts?

Also, anyone out there have a set of used steel half shafts for sale? If there are some around, what kind of $ do they usually sell for?

Won't sleep well tonight thinking about this one. All opinions welcome and appreciated.

Jim VanDorn said in post #7 that he might have a set upstairs at his Pirate Lair.
Drop him an email, see if he's interested in parting with them.
