New guy to this site and have a few questions that I'm sure are beat to death, but here it goes: Have a 1985 K5 Jimmy and looking to add some bits and pieces. I have already swapped in a crate GM 350 in place of the 305 and had the tranny gone through at the same time so it runs like a top. 1) I have identified the front and rear axles as GM 10-bolt's but have no idea as to what the gearing is. Can someone point me in the right direction for possible resources for decoding the gear ratio? 2) I've been thinking about putting a 4" lift on the rig and some 35x12.50's on the stock wheels (love the classic look of those). Are the 10 bolt axles up to the abuse that 35's will put on them? Suggestions of what to change out if they're not would be helpful (not interested in swapping axles). Extreme off-roading isn't what I'm after, just some height to bust through snow drifts. 3) Recommended paint type/brands for re-squirting the fiberglass top. It's starting to peel and bleed off when it rains and a little preventative maintenance is in order. Sorry for the long 1st post.... this is a great site!!
