After years of promoting only GM seals we have found a few manufacturers who were able to get the closest possible quality of original GM seals and we have put together a mini-kit of the basics. The seals we are carrying are manufactured by 2 different companies we have chosen after a lot of research & development and feel confident about the quality. If purchased separately, this 5 piece kit would cost $289.90. Set includes DS and PS lower door seals, DS and PS hardtop roofrail seals and a hood to cowl seal.
