If the difference in mounts is 5$ id say go with a sponsor over a non- sponsor, Also, there is a good chance that if you ask most sponsors give a discount.
Thanks it's good to know I should be able to easily take the alt. bracket out should I need to. I will try and update this thread whenever I need to replace the alt., so I can comment on the bigger bodied alternator, I am sure it will be fine.
They are a Supporting vendor which carries some weight with me. I saved like $30 or so with my discount! They kept me up to date on when it was being assembled, shipped, etc. and when I had questions they were very helpful. They did forget to send a couple of the pieces of hardware. When I called about it he seemed genuinely disappointed they missed that and even used the word unconcionable to describe forgetting a few small bolts. They were sent out immediately and I was left with the impression that they genuinely care and would bend over backwards for their customers.
