Both ford and AMC used the ford duraspark distr on their 6 cyl's so the reluctor from either can be used. Just look up an early to mid 80's 6 cyl.
You need to check the ID of your distr. If it is the smaller delco then you are better off with the mopar pickup mounted on the stock baseplate and then your choice of a mopar or ford reluctor.
The mopar reluctor has a larger ID then the ford.
If you go to binderplanet and look in the "start here" injection forum FAQ's you will see many different distr's converted for use with EFI. 4, 6 and 8 cyls.
Here is the studebaker 289 prestolite distr.

I don't have a 235 stock distr on hand or I could tell you what parts would be best for the conversion.
