I have a 914-6 GT Replica built using a factory 6 engine case. The motor was built many years back but has little time on it from all accounts. It has an Electromotive Crank Fire set up on it now. The engine runs great and has good compression. Given I'll be using it for vintage race events and the engine is out we decided to replace the crank fire with the 123 distributor setup. Most vintage race groups would not allow crank fire to be used.

Given I don't have a distributor now I'm missing the clamp. I found one for sale at aasales. Do I need anything else or will this clamp provide the correct spacing to the drive gear?

The 123 dizzy comes with the clamp as part of the casting. No need for your clamp

That's not what I see with the Dizzy and I talked to Ed yesterday.

100% they do for a 911 based engine. I have one in my car. Will take pictures later.

What size engine do you have? If its a 2.0-2.2 then the clamp you specified looks like all you need. 2.4 and up come with the cast clamp

Thank you. It's a factory 914-6 engine case, 1970 2 liter. It is no longer stock displacement, etc. but this looks like the clamp I need. Ed wasn't sure if it was just the clamp that was needed but per the diagrams I've seen it looks like that should do it.
