The genuine MIS is no longer made.
I got mine from a Norwegian rallycross escort.
Mr Martin schanke, the rallycrossdriver from Norway, can get new, reproduced inlets, made from the same equipment that MIS used before. I bought one of him, before i got a hold of the genuine one. The price was about £2500.
The gold one is the one Martin can/could get.
If you want, i can call him, and see if its still possible to get them.
