The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi everybody, Glad to be here with fellow GM truck admireres. I am currently in the process of restoring my 1987 Chevrolet V10 truck swb dual tank Silverado. Took it down to bare metal, new cab corners, rockers, and floor pans. New/used rust free GM passenger door, wheel wells and fianlly the biggest and hardest part to find a rust free(yipee) swb dual tank bed with factory tail gate(bonus). Put POR-15 on everything after being blasted, oh new gas tanks and mounts, polyurethane bushings all the way around. Flowtech headers, TBI spacers. Ok the list could go on and on so basically rebuilding the truck from the ground up. I'll try and post pics when I figure out how to do it.
I do have a question though? Can anyone give me step by step instructions on how to change the vent window seal? Is it hard? I know new vent windows are about 300-400 each depending where you go but the budget is quickly shrinking and still need to buy tires and paint, carpet, back window, speakers. Any help woild be appreciated. Thanks, Andy
