A few of you may noticed that i sold my parts on CF the other day, but here is a list of parts that apparently Jeff Kopp of Superior Chevrolet put together (genuine GM parts that can be purchased ANYWHERE - i chose to buy mine at Fred Beans

parts are as follows (you can do multiple part lookups on their site for ease of use)

*Prices current as of 1/04/02

here is info about the ADAPTERS to adapt the C5 or Z06 brake caliper bracket

the place i got mine from said this

The brackets to mount the C5 brakes on a C4 are $95 ea. The 14mm blots and lock washers are $40. We are selling the brackets and bolts for $200 plus shipping.

his name is rich gardner

and the guys at car-vette referred me to him

and Ed Salinas is the one who referred me to car-vette, as Ed Salinas is one of the originators of the C% adapter bracket, however, he did not have any parts in "stock" and didn't see himself producing any in the forseeable future.

he can be reached here



i couldn't find a link to purchase JUST the brackets on his site, but you can email him for the info - i think it cost me like $26 or so to ship them here.

these prices may not be accurate - as i just pulled this data from the text document i have saved on my work computer - and i believe they came off of SUPERIOR CHEVROLET's website.

PLEASE DO NOT QUOTE this thread if you reply - as i'll be making changes throughout the week on further information and updating the prices as i search them out from fredbeans

you can also order from gmpartsdirect, but i think their shipping costs are much higher - and they don't even give you an accurate quote until AFTER you order!

*still under construction - so i will keep updating
