Buick V6 modification, Info on transmission mount spacer size. Options

[pistonboy]

I am trying to complete a 914 that was never properly modified. It has the Buick V6 4.1L engine. The back half of the floor and many other parts have been replaced using parts from the Canadian company (Restoration? I cannot remember their name.) It is now stiffer than factory. Pinched one inch heater hose between engine and radiator has been replaced with 1.5 inch steel tubing. Many other things have been done to.

I have a question about the transmission mounting because it appears a spacer is missing at each. Present is the bolt from the transmission mount to the offset block. The offset block is present as is the bolt through it holding the transmission. What is missing is the spacer between the transmission mount and the offset block. Can anyone tell me its size? I can make a new one. I assume it is a segment of steel tubing but I do not know how long it is. Perhaps a stack of washers will work if nothing else. Does anyone know what size this spacer is?

It is a Renegade kit with their name and phone number molded into the adaptor plate, but I question how receptive they will be to someone with one of their old kits.

Thank you?
