Nice AD!! I take it you cover the aluminum with a material to match the seats? I can see where the aluminum would not warp or bend with moisture and heat, what adhesive did you use?
Wish we all could come up with a "vendor list", though I realize some vendors are sponsors of this great website. Seems to me from reading posts here for about a year now, there are some "crappy" parts being sold!! Would like to see a list of who has the best quality product available for sale!
