6 volts or 12? Electronic ignition or points? what year? A little more background information would help a lot.

On Bubba's advice I run a Bosch Blue coil 00012 with internal resistance on the 8ba in my '39 p/u converted to 12 volts. It has a Bubba Chevy conversion distributor.

Both Amazon and Autozone list them. Both for just under 50 bucks. Other sources as well according to Mr. Google for similar and more $$

Get a coil from Skip Haney in Florida and you will not have
coil problems again. And he repairs them at no charge if it
ever fails. He has been doing them for 25 years. Ask people
on this site about them. G.M.

Like I said; how can we make commendations with no information? We don't even know it it's an integral coil or a can type , for cripes sake.

His avatar is a Model "A", but this is the Early V8 section, so that's not even of any help.

A friend bought a ‘35 convertible sedan about 10 years ago.
I rebuilt an LB and put in it with a ‘35 distributed with an adapter for a modern coil. 6 volt.
Always had trouble starting it after it was run foe a while.
Would fun very poorly when it got hot. Wouldn’t star if he shut it down.
I got 3 new NAPA coils and tried them but never satisfactory.
Got to where he didn’t trust the car. Usually had to wait about 40 minutes before it would restart.
THEN... he sent a stock coil to Skip.
When he got the coil back he brought the coil and the car to my house. It would not restart.
I replaced most of the exhaust system and changed the coil. Fine.
I drove the car back towards his place in Oakland.
A bout 12 miles and I stopped at a tire shop where they knew me in Oakland and I shut off the car.
After telling the owner why I stopped there I hit the starter button and it STARTED right up.
I drove on to the owner’s house in Piedmont, about 5 miles, shut it down and it started right up!
Now about every 6 or 8 months he calls me to tell me how much he likes that old Ford ever since I put the Skip’s Rebuilt Coil on it. Just loves that car.

Skips coils are GREAT. (Just don't leave your ignition on. It will fry a coil in short order. (Don't ask me how I know. Twice.)

He's been back on the forum yesterday SINCE the request for clarification, but he has obviously ignored that. Reading back thru his past posts, it appears that he's a real novice, attempting to put a 59 AB in that Model A roadster, for what it's worth. I don't have a whole lot of desire to lean over any farther backwards for someone that can't help-out just a little! And who could have guessed....we have yet another infamous referral from George.

OK, I'll go ahead with guessing. Since he may be asking about a 59A in a Model "A". I'll guess "can coil". If that's the case, you cannot go wrong following "Charlie ny"'s advice.
