Designed to drive HEI module plate...

I have a couple of the design to drive brackets, they are really nice.
One thing though, if the hei module ever goes bad, you would have to pull the distributor to change it.
Also if you go with the hei, pentronix sells a sweet module that has a adjustable rev limiter for $70.

The fact that to replace the module is one drawback, and the other is that the 4 pin modules are prone to death from low voltage.
They solved the low voltage problem with the 8 pin module.
Currently Pertronics only sells a unit for points distributors, and nothing for the OE electronic distributor.

Some of those modules have a very small locating peg (if it ain't there then no worry). On this non chebby mounting you wouldn't want it if it is there to keep the back from laying flat/haveing solid heat sink contact. & cut it off if it is there.

Exactly, the 4 and 8 pin modules both have two plastic locating pins on the bottom side that need to be knocked off so the module sits flat on the heatsink.
Been running an 8 pin module for 5-6 years without a single failure of any kind.
