Just a few quick questions about converting to a 91-92 type high rise spoiler on a regular Iroc. i tried a search but couldnt find anything of substance for my questions.

1. Will the holes currently in the decklid work for mounting the new spoiler?

2. Any good suggestions for filling the holes on the rear quarter panels that will be open after the swap?
I figured on this one I would MIG weld the holes shut using a penny held up to the back side that would provide a nice backing that the welds will not stick to.

Other then these items, anything I need to consider further?

 

Here is a shot of the holes in the rear.

 

I'm pretty sure the hole in the top of the deck lid would line up. But I'm not 100% positive...only 95% sure.

 

Nope....the holes won't line up at all...atleast they didn't on my old 84 Z28 when I cloned it to a 1992 Z28....I had to weld EVERY hole up...and drill all new holes in the deck lid. The holes do come close...but....not close enough....I used a MIG welder...and it worked great...no problems at all..

 

Your best bet would be to go to a junk yard and get a decklid without any holes in it, then drill the holes for dirll the holes for the spoiler and weld some steel behind each hole for the side spoiler holes and fill the little area in with bondo or you could weld that in as well and sand it smooth.

 

On the side holes, you could either weld a washer inside them and then fill the center hole up, or just use a brass hammer behind it. The weld will not stick to the brass hammer.
