[louied]

 am driving myself crazy trying to figure out what works and what doesnt..

i have a stock si-12 running now ( 90-100amp), and i want to upgrade to help with a plow I just picked up..

I want to upgrade to a cs-13d or cs-144 140-200 amp.

problem: i am getting conflicting replies from the web and other forum members on what fits and what fits with additional brackets..

What works ?

87 full size blazer
stock si-12 w/stock brackets
350 ci
mounted on pass side

thanks for all the help.

You should be able to fit the CS144 in your Blazer, I recommend the Extreme Duty Dual Rectifier http://alternatorparts.com/Extreme%20Duty%20Dual%20Rectifier%20CS-144%20type.htm Which should directly fit into your vehicle. You may also need the D1-W1201 or D1-W1204 adapter plug depending on whether or not you have a no charge warning light in your dash.
