I make a TDC pointer with crank trigger mount for the Jesel setup and I have an optional 3/8 pickup mount. I don't think that Doty ever tooled up his 3/8 pickup mount.

If you're looking for the DMI bracket you can buy them from Mancini Racing or direct from Doty. I think GregZ went out of business and moved on to a different gig but I haven't talked to him for a long time now.
