Here is a link for an excellent source for GT suspension frame parts. My good friend Vinny now owns this store...third generation. Amazing bike shop. Vinny bought pallet load of parts after Pacific took over GT. He many times has items he does not have listed so if you don't see items you need pre-1999 just message him through his web site and ask. He is an eBay.com seller and has a store there as well. Great source
