I just got a set of brackets to put discs on your '88-'98 chevy, bought another project and decided not to sink the money into putting rear discs on.

Here's the link to the ebay auction http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=7947337572&ssPageName=STRK:MEWN:IT it will give you all the info you need. Never used, opened the box they came in to look at them, and put em on a shelf. Only had em for 2 weeks now. Paid $80US plus shipping, make me on offer.
