Would you have the Denso part number for the small alternator you pictured. Also would you know the amp rating and body diameter.

Trying to locate an extra small alternator for my '32 roadster build with pinched rails, so room is very tight.

Thanks, Tony

I looked on the one I've got, no number, but they're commonly refered to as "mini-alternator". If you look on ebay for example, you'll see lots of them that match the one in the picture. From there you might get a number to look for one locally. Or check with a Kubota (maybe other manufacturers of small tractors as this unit is very common to them) dealer.

The nominal diameter (not counting the mounting ears) is 3 1/2".

The tractor ones are often 40 amp, though I've seen them also listed in 50 and 60 amp as well.

Thanks Bob.
Did an Ebay search plus found Powermaster have them listed. The max amps I can find on Ebay is 60 amp but I'm not sure that rating is correct as Powermaster list the same part number as only 50 amps. Ideally I need 70 to 80 amp, does anybody know if they are available higher than 50 to 60 amps is this small case size ?.

I use the alternators found on Mitsubishi's, they are tiny and very powerful, if you get one from a luxury Mitsubishi it will be 90 amp plus.
Kubota are also tiny but not very high amps.
