I'm trying to identify a couple used parts. Can anyone offer some advice on identifying a jack and side glass? I'm pretty sure the jack is from a C3 but don't know what year or if it matters. The side glass does not say Astro Vent so I'm not sure if it is replacement glass or if the label wasn't on later C3's.
Thanks for any help you can offer

Sorry, no pics yet. I'll try to get my hands on a digital camera and post something. For the jack I was wondering if there were numbers to look for and where they might be. I didn't see anything on it. The windows I am sure are C3 but I don't know if there were changes in how they mount. I believe the glass is different for a coupe and convert but don't know what the difference is.

I'll get pictures.

As a matter of fact it does look like that. It even has the rubber deally on the lug wrench. So that is probably correct for 77 to 82?:huh:

Thanks

I would think so. In looking through a restoration guide, it looks like only the 68' was different. It had a smaller base 6"x4" where all the others are 9"x5"

The Astro-Ventilation door glasses were used on the earlier cars; plain glass on the later cars. Sorry, but I can't recall the year the Astro-Ventilaiton was dropped.

Jacks and jack handles are the same except for the '68s.

My advice would be to purchase the assembly instruction manual for your year. The AIM contains diagrams of how the car was assembled and original part numbers. Having part numbers helps considerably when chasing parts, especially if running changes occurred during the production run.

Found some info on the glass. "Corvette restoration Guide" Book says the "Astro Ventilation" on the side glass was eliminated toward the end of the 1974 model run.

Probably right. My '74 coupe had the Astro-Ventilation on the door glasses. If I recall, she was March production.

I was just reading the NCRS guide on this. Like 6880/mike said the astroventillation was dropped at the end of '74 but some carried over to use up stock on early '75. side glass should be two place date coded and (IIRC) coded as M74 (coupe) or M75 ('vert). If you want I can verify the date and use codes tonight when i get home. The easiest way to tell orig glass is the smooth or wet look to the edges not rough or frosted.
