Could anyone recommend me Electronic Distributor Conversion Kits for 1963 225 valiant?

I fear the OP is getting confused. I think Pertronix will only fit in an original points distributor (1970 down). If so, Pertronix Ignitor II or III is best. I understand the original Ignitor requires keeping the ballast (might depend on coil). Pertronix biggest advantage is it all fits under the cap. Cheaper is a Crane Cams XR700 optical conversion. I have several I won't use, so PM if interested (some might be new). But those use an external box and require the ballast (i.e. a bit dated electronics). A GM 8-pin HEI is probably best, but more work & requires a 1971+ e-distributor.
