There are about 4 different gasket sets here there is enough for the large 20B sequential Twin Turbo from Cosmo large intermediate and also for a FD rx7 twin turbo on top of that I have outlast gaslets and also t2 rx7 downpipe gaskets all in good shape some are brand New if you only need one set or gasket specifically message me and we can make an auction  for it if you service or build these you know this is about 1300$ new in mazda oem Metal gaskets which are the most reusable  not reusable gaskets you will ever find these are all like brand New some have a little run time all are reusable the older t2 second gen downpipe gaskets are the least new..

If you need measurements from these gaskets let me know
