Pics of the '75 Blazer... aaaalmost finished!

I'm installing a dual battery set up similar to the Blazer Chalet, so if parked, the battery can drain, and not affect the engine battery and starting capabilities. Of course, the alternator will charge both.

I'd like to do this on mine. Where could I find more information?

Spencra, the roll bar is standard equipment on these years Blazers. You may be able to find one at the salvage yard, or by posting a wanted ad here on the boards. A lot of people remove the roll bar when lowering their truck, especially 2-wheel drive customs.

I have seen two different versions of the roll bar. One version (like mine) the angle brace mounts to the bed floor, and a second version in which the angle brace is a little higher, more pronounced, and mounts to the wheel well tub.

Badpeanut, there are several sources for dual battery set up information. Since it was a GM installation on the Chalet and on some diesel applications, there is an assembly manual diagram (attached). You can get a battery tray for the drivers side from LMC Truck (Longs Motor Company). And finally, you can get the relay assembly from stereo shops or auto parts. Custom auto stereo shops are used to dealing with lots of batteries and alternators so they should be able to set you up with the remaining pieces parts necessary.

I hope this information is helpful to ya'll.
Greg.
