Re: 1992 Upper Radiator Shroud Removal
Yes. Very hard to get them. I used a small 8mm wrench for the ones I couldn't get with a 1/4 " drive ratchet, extension and universal joint.

Re: 1992 Upper Radiator Shroud Removal
If I remember correctly, it was just a couple of bolts. I disconnected everything from the top. Remove the hoses from the pump. It doesn't need to move far.

Re: 1992 Upper Radiator Shroud Removal
Did you get the 3 on each side? 8mm head.
Also 2 on each side down by the frame rails.

I used the DMH-C2550NEX with Crutchfield's adaptor cable using the original Bose amp/speaker combo.
The only mod needed was to trim the plastic behind the radio for some clearance.

Re: Oil leak
Most likely the crank sensor, but there is oil a bit higher on the block. Maybe being blown around?
When Mark built the 415, he had a leak at the crank sensor as well. Haven't had a leak anywhere...

Re: Bose replacement speaker chassis?
Hmmmm... looks like Corvette Mods was bought by Top Flight Automotive.
Speakers not available there.
I'll try to find the boxes and get the Bose part number for the speakers.

Re: Mecum - LT5 engines
These have been around and for sale for years. I doubt they will be a bargain, if they sell at all.

Re: '91 ZR1 different Mufflers and Control Arms?

Re: Saw a Unicorn.
Looking through the color combinations in the registry site, it looks like one of the most rare is a 93 white/white. Only made one.
