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)

I have 1990 #608 and mine are steel.

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!!

Re: Half Shaft Mystery
 

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.
