Whoever is installing the front and rear screens, should be able to buy the seals from Windscreens O'Briens.
They supply a good quality repro part, @ about $120.00 front seal and another $120 rear. They can also supply the mould clips, which have to go on before your screen goes in.
Toyota can still supply glass run divider seals. Boot seal, try Corona and Corolla of the late 70's, and cut to length.
