yeh that test mount i got is just like those gen 1 mounts then, but i tried gettin another and gary was useless as usual.
so i'm tryin some of the BC ones which measure the same diameter to see if they happen to be the same thread. If not i'll get an engineering place to make up a copy of the test mount i got from daiyama.
Ahhhh shit yeah I didn't notice that little collar thing..
Surely you could cut thread further inside that though.. Probably be tight!

or I could just get you two first gens... if someone dont mind
