Thanks guys, I found a part from MSD for distributorless engines for about $40. I'll have that on Monday so that should solve the Tach issue. Yes you have to get the PCM reprogrammed to get rid of the passlock antitheft circuitry. A warning. I had an extra spacer (scallop ring from McLeod) as well as my adapter plate and the trans was back just a hair to far. Step on the clutch and the internal throuout traveled to far and came apart. Everything is now back together with one less spacer and works great. Also took it to the muffler shop and had 1.5" OD tailpipes installed that look like stock Healey except the're on the wrong side. Now it just sounds like a very healthy Healey!
