[Fot] TR-3 - Distributor Dimension

[Jack Wheeler]

Does anyone have a complete TR-3 distributor laying around?  I need to know the dimension from the bottom of the distributor housing, where it sits on the block (without the hold down clamp) to the bottom of the drive gear (ignore the 2 tabs which interface with the drive gear).
In my race car, I used a Datsun B210 electronic distributor as my backup ignition.  Primary was a crank trigger.  This Datsun distributor slid right into the hole in the Triumph distributor pedestal, But the shaft was a little bit longer.  So, I had to shim it with a spacer between the bottom of the distributor body, and the distributor housing.
I recently picked up a new Datsun distributor on Ebay, and I am preparing to put it in my street TR-3.  I'm trying to get all the preparations done before I take the Lucas distributor out of my TR-3, as I drive it regularly.  The dimension I need (above) will allow me to make up a spacer of the correct thickness.
Bryan Braselton, if you read this and still have the distributor setup I had on the car, maybe you can measure the thickness of the shim between the distributor and the distributor pedestal (I think it was about 5/16" thick).  That will save me from doing the calculation.  I have a wiring diagram for this electronic distributor setup if anyone is interested.  The Datsun distributor was about $65 on Ebay.
Thanks for any help you can give me with this.
