When i decicded to go HEI on my 235, I went to one off the local auto recyclers(aka wrecking yard). Found a car with a 250 in it.yanked the distributor and ingnotion leads from it,took it home made the mods to put it in the 235, made sure the cap was clean and crack free. Dropped it in , set the timing, 6-7 yrs later, no prolems. 50 bucks and my time...original,honest gm parts. If i wanted to go back to points, i have enough of those distributors to make 1 or 2 that will work. I too,am leary of alot of the "new" replacement parts and learned many years ago the value of recyling ussd stuff. Now there are somethings one has to buy new and it takes some research before buying. Also i buy alot of stuff thru anyone of the 3-4 local parts stores and usually can get what i want. Product support,warranty,cores etc are easier deal with locally. Plus the added bonus of building personal connections, i do better with that than someone one the other end of the phone i have never met.
Having read through a lot of post on this site, I see alot of people rely on Amazon, EBay etc for their parts,at times for very good reasons. Lets not forget about the local stores just down the road who can very capably us out. As been said on here before,get to know the best parts guy and he/ she will go the exrta mile. I also dont mind helping them learn something new.
As replacement parts,,,and quality of said replacement parts gets more and more questionable,its up to us to leg out the best choice for us,and figure out a workable alternative. Many on here do that, and its commendable.
Enough of my ramble.
