I'm sure that this has been amply discussed, even to death, but I wasn't satisfied with what I found in the Archives. I'm going to take the plunge, and install a Pertronix breakerless ignition system in a '69 1800 w/ a stock B-20. The car has a Weber conversion, and I just drove it from Seattle to Washington, D.C. It ran flawlessly, but the points kept closing up on me., so,...

Here's the rub, I have a whole bunch of distributors to choose from, as I've been parting out cars for almost 15 years. The car now has an aluminum bodied vacuum advance type dizzy, that has a "085" on the side. It had a vacuum retard type as stock, back when it had Strombergs on it. When the Weber was installed, it ran so cr**** that we went to the 085 type, and it was night and day! I also have several distributors w/ "086" and a bunch of others I'm going to list below. Some of them are of the vacuum retard type, which I think were for the first "smog" controlled engines.

Anyway, here's what I have, and I would welcome any comment as to which would be the best candidate for an electronic breakerless ignition set up. I also have a Mallory UNILITE breakerless distributor (w/ a tag reading 236 1001) which I inherited somewhere. What I'm aiming for here is reliability and ease of maintainance, not out and out performance. If I can get both, well,...

Metal body distributors;
a.) 0-231-153-009 JFR 4
b.) 0-231-153-002 JFR 4
c.) 0-231-153-003 JFR 4
d.) 0-231-146-078 JFUR 4 (w/ vacuum- retard?)
e.) 0-231-146-099 4 (w/ vacuum- retard?)

I think these next ones are the old B-18 122 standard metal body types;
f.) VJUR 4 BL 33
g.) VJU 4 BL 33
h.) VJ 4 BL 34

Now the Aluminum bodied distributors;
I.) 0-231-178-007 JF 4
j.) 0-231-170-086 JFU 4 (vacuum retard type?)
k.) I think there may be some other types in my various B-18/B-20 fleet, but I haven't looked recently. Sometimes there can be too much of a choice, so I need to narrow down the likely candidates. I believe that the "U" stands for "unterdruck" (= vacuum in German). Thanks again all, you d' best!
