Hey guys, new member, so I hope I'm in the right forum. My wife and I recently bought our '91 GMC C1500 (5.7 L 350) and I noticed the volt gauge showing low voltage. The truck has had a few small issues that could have been caused by this and I'm wanting to change the alternator asap, but I'd like to upgrade from the 105 amp to a 120-140 (nothing too extravagant. Possibly adding an invertor in the future). Will I need to upgrade the fuse block or anything else, or is it just a simple swap one for the other?
