Alright so I decided to take some pictures as I did this comparison.

The alternators I am comparing are as follows:
Obd1 D series from a d15b7
Obd2 B series 3 pin alternator from a Canadian integra
Obd1 F series from an accord
Obd2 H series alternator



From left to right, H/F B D

You can see that B series and F/H mount in the exact same way. D series are offset differently.



Here are some pulleys. D B H in the picture. The D series bolts on differently than the other types.



This really shocked me. Here's the D series pulley on the F series alternator.



Here's the D series pulley on the B series Alt. I know a 3 rib pulley exists, but I don't have one to compare. It was on the obd0 civics I believe.



Just for fun, here's the H pulley on the D series alternator.

I will weigh them as well. This solves my issue with using a smaller pulley to clear the framerail on my H2b using innovative's h series Alt relocation.

Weights:
D series is just under 10lbs.
b series is just under 11
same with F and H.

So which alternator did you use with which pulley?

What chassis? Any pictures?

In an EF, with an H2b, using an accord alternator with the B series pulley.



I still had to pound the frame rail a bit to flatten a bump that would be in the way. This offers the best clearance however.
