Where's the best place to buy w/strips for my T-Type?

[1980malibuman]

I need to replace the Door Seal weatherstrips around both doors, the Side Window Belt Line Outer seals/mldgs (to seal against the glass) with the black trim pkg, and the Anti-Rattle T-Top Weatherstrips. Who offers the best quality parts that fit the best and at a reasonable price? Does anybody here have these parts and wants to sell them? The car is a 1986 T-Type. I also need both rear cloth inserts for the lower trim panels on both quarter panels in grey cloth for my 1987 Turbo T.
Thanks.
