Model a distributer help

[peter schmidt]

I just pulled apart my distributer to put in a modern upper distributer plate and install my new style cap wires and put in new plugs. The car was running but ruff and would stall out and miss I compression checked it it has 75 75 77 and 77 psi on the cylinders from front to back witch seems good from what I've read. I also have a fuel problem but I want to get the ignition system up to par before I mess with that. The car has been converted to 12v very poorly so I want to redo all the wiring. I ordered a modern upper plate for my distributer a new lower plate with a extended wire new rotor and the modern style cap and wires I pulled the old cap off then the upper plate and there is no lower plate even in the distributer I'm new to these distributers so I have no clue what's goes where as I have nothing to go by right now the wiring is so bad I'm not gona use it there's splices not covered and all the wires came in through the distributer from the driver side front hole there frayed and exposed with random connections to other wires just bare and twisted together. Does any one have a breakdown of a model a distributer and a wiring diagram for one? I know it's probably a lot to ask but I am lost. Thanks
