Heh Blue Flame, is the picture in your avatar a Morrison Escort car at Sears Point? I tried enblarging but the resolution is not good enough.

Hi John. Not sure where it was taken but it is the #99, for sure. This is the car that I plan to bring to BG in May for you to look at. I'd love to end up with a pic of the car wrecked at the track and speak to you about it all. Bring back any memories? Are you at the wheel in this picture or is it Percilla?

And Eric, Thank you for letting me take a look at your cars. Never again in our lifetimes will such opportunities show up to own such unique Corvettes.

Ok, Today I installed the driver’s side front shock servo. This cleared the SRS light. I am also somewhat baffled by the air deflector for #004. The whole deflector was a bit askew. I had previously removed and heat straightened the chin spoiler. I noticed the air deflector "wing" was missing. After looking at #074s assembly and my L98s I determined that an L98 wing would work. I found a used one on Ebay. Well I was wrong! It appears that the mounting brackets on #004 are entirely different from the L98 and #074 (see picture):



#004 has a slight bend and three rivet mounting holes. #074 is straight with 2 rivet mouning holes. The used brakets have 2 mounting rivets.

Eric, do you know what an 88 production car bracket would look like compared to the #004 89 prototype ZR1? Also, I wonder what it looks like compared to Tyler's car?

All good questions. Not sure. The parts book calls out one set of brackets for all year L98 wing ends:

14058299 LH
14058300 RH

The picture looks like it has 2 rivet holes:

Is that a parts book for 88 or 89 production cars? Maybe there wasn't a production page for the 88 or 89 ZR1, even though it would make sense to have a book for the 89 in anticipation to the planned 89 ZR1 release.

Does the bracket on your #004 have a part number on it?

[1989ZR1#74]

No part number that I can see. THe parts book is for up to 89 not including ZR-1. I was just showing that it appears that the 88 part is the same as the part I bought.

The more I look at this the more I am thinking there may never have been a "wing" on it. There is no evidence that the rivets were drilled out or broken off. The brackets look untouched. I have some preliminary engineering drawings but they do not show the wing. On the other hand I have seen the wing on other earlier then #074 cars and I think #016 has one.

I have a 88/89 Prototype Program assembly document for ZR-1 sprcific parts and it does not list a ZR-1 only chin spoiler. The PAD shows the radiator assembly is a ZR-1 specific item, below that area everything would be production 88.

I think the change happened when the cooling pods changed, which my rusty brain thinks was in '90. The '86 cooling pods are hand laid fiberglass that were so "unique" that the underside of the hood reinforcements had to be cut out. A center airduct from a '90 might bolt right on, or the engineers might have just rigged it, knowing it was preproduction. I also think there was a different (deeper) spoiler for a Z51 car.
