I recently had my glass replaced in VA. no trouble at all. i did NOT go through my insurance or their chosen installer, Safelite. mostly b/c I was recommended by my local TLCA chapter to use a small local shop. cost me somewhere around $500 all in. he even cleaned up and treated some corrosion that was happening in the glass channel, and he was WELL versed in the Toyota install procedure.
i sourced a new gasket from Toyota of Richmond VA, but could have also let the glass shop source a gasket, which I think was aftermarket. i thought it best to go Mr T.
glass shop sourced the glass. Mr T glass is no longer available, as you know
my glass shop does all the work for the local toyota (and other) dealers. he keeps his own small shop and does installs there on days he's not at a dealer. so maybe call or visit your local dealer and inquire who THEY use.
