The only differance between the two distributers is the
oil pump drive shaft. So, for, they're all the same.
I also needed a short distributer for my intake. The shortest I could find for my application was the Mallory Unilite.
I looked at the blower specific distributers, They're much shorter but their advance is limited to about 12-14*, IIRC. I'm almost willing to bet they could be modified for more advance, but I'm not sure. If the Unilite had been too tall, I would have tried that.
