And please, please, please avoid anything with the word Pertronix. A couple of months ago I showed proof (with a de-magnetized ring from a Pertronix unit) of why these fail. Anybody buying one is asking for trouble and wasting a great amount of money in the process. In my opinion there are less than $10 in parts in this unit.
Also...Around a year ago I showed how you can convert a common Chinese HEI unit made for the 230/250 (sold on eBay for $60 or less including shipping) to fit in the 235 using a ring collar, a hacksaw, a bench grinder and a file...and a couple of hours tinkering. Those are all built using GM parts and they work fine. If anything in them fails, it can be replaced using GM parts. It will come with the "coil in cap" style or you can use a plain GM type cap with a remote coil. I am using a clone I bought in 1997. I converted it to the 235 and haven't had any trouble with it.
Good luck. If you stay with the points scheme, please contact me for a lifetime condenser option.
