I 2nd BradB's recommendation - I've found Steele to have top quality pieces, and they'll work with ya to do stuff they don't stock - I sent them the decent OEM rubber off a pair of NOS TF panel doors I got and they repro'd it exactly and perfectly [if you TF guys need the back door rubber, they have it even if it's not listed - inquire!] - they also have the rubber for the clamshell doors and glass I think
Steele makes all of that rubber you get from many suppliers who list it as "made in USA"
