I'm sure others will have more information but this is what I have:
I still have the 235. I'm using a S10 HEI distrubutor and external coil. The wire from the ignition to the positive side of the coil had a resistor. My instructions said to remove it. My distributor has two wires. One wire (pink) goes to the positive side of the coil and the other (brown) goes to the negative side of the coil.
Hope this helps.
