Although this post is primarily about 80's this could be considered relevant, Today I'm fitting a set of BEB's to an 80 I have. Although a fan and user of RTV silicon sealer I thought I'd try the proper Toyota stuff.
Down at the dealer I asked for a tube of the right stuff.

Not my concern about the price ( I thought)
Lad came out and apologetically said " best I can do with your discount is"......
£95 + vat.........
Having had a look on a few platforms it can be bought a good way cheaper but still a ton dearer than a tube of RTV so RTV it is.
