Hey guys and gals,
Not sure if anyone has a source for the 521 glovebox, but on ebay there is a company that is doing several other models but not the 521. Just got one for my 312 and it's pretty nice and sturdy. If someone has a half decent one that they would be willing to send in to have a template made, they would be able offer these up. Ebay id is musclemaniac5. Directo contact is Mike, mw74cuda@netzero.com Check out there store for what they are making.
And, I am in no way affiliated with them and make no profit either. Just hoping to get a glove box for my 521.
Mark
