Yes, same light for either. The real choice is whether you use an inductive vs an on-plug type light. Again, either will work but the inductive is usually more convenient if not a bit more finicky. Some lights struggle with multi strike ignitions.
I have had good luck looking on Marketplace or Craigslist for used ones. $20 or less usually. I have a couple of the old chrome Craftman inductives that have served me well. Bought both used. Only need one, but the last one was still in it's box, looking new for $10. Couldn't say no even though I didn't need it.

Been using the old chrome Craftsman lights since the late 70's or so. So far, so good. Same. Non-dial back style--I just use a timing tape. Even used it with my old MSD 6AL box on my last car and it did not seem to mind..

Been using the old chrome Craftsman lights since the late 70's or so. S5o far, so good. Same here. But also bought a,Sun Engine Tune Up box set It is light, vacume, a line tgat screws into spark plug holes to test compression and that gauge so yiu can also compress to swap spring's or seals. And of coarse the Main bix that shows dwell, RPM ect. And a few other thing's ijjn there All like new

Yes. You do not want the vacuum advance to influence the initial setting. Just make sure that the carb does not have a resulting vacuum leak that could raise the idle.

Typically what you are setting is base timing. There should be no vacuum advance due to vacuum (plug line) and no mechanical advance due to high engine speed (maintain specified idle speed). If you are setting total timing or something other than base, that is another conversation.

Rev the engine until all the mechanical advance is in (vacuum advance disconnected). The rpm it is all in will be determined by the springs you have in the distributor. Put Mr. Gasket #925B in to get a quick advance.
Set the total timing there. Let the base timing fall where it will. I would start with 34-35*.

ok, thanks for the clarification. i thought, at one time anyway, there was a mr. gasket spring kit recommended that was for GM distributors. not that i can be "cornfused" easily............. They were available for GM type distributors the last time I checked. I bought 5 or 6 of the 95B kits to have them as needed, I do weld up the advance slots on the old type stock Mopar distributors and adjust the new type so I can have 12 to 16 degrees initial advance at a low idle and 34 to 36 degrees total advance above 2000 RPM

i have welded the slots as well Cab, and i have a couple of those limiting plates here, but i have never tried those yet. a lot of performance can be gained by fiddling with the distributor weights and vacuum advance ! well worth the time trying different combinations, and a distributor machine will help, but not really necessary if one does not have access to one.

For some reason in the past few years I've had a couple timing lights come my way, still no digital ones or dial back ones tho and some are the older style that go in line with the plug wire. i have welded the slots as well Cab, and i have a couple of those limiting plates here, but i have never tried those yet. a lot of performance can be gained by fiddling with the distributor weights and vacuum advance ! well worth the time trying different combinations, and a distributor machine will help, but not really necessary if one does not have access to one. That's one nice thing about the mallory built mopar performance distributors, that you can you don't have to weld slots or change parts other then the springs.
