Small update. Drove the blazer in the snow for the first time and it pretty much went how I thought it would. The rear brakes lock up first so if I'm not real. careful the back end wants to pass the front. I think I will swap lines on the master and use some adapters and see if it will help otherwise I'll Have to plumb in my adjustable prop valve and turn down the rear brakes. Also the four wheel drive will just fall out of 4hi when driving. I cut the rubber boot and that didn't help. Ended up taping it back to the console with a roll of electrical tape to get to work. I hope I can just adjust the linkage and its not an internal issue in the tcase. Prob won't get much done for a while. It's "real" winter here and my extra large garage only has a 7 foot door. Plus I have other vehicles that need attention first.
