Hopeful new owner, have a few questions

[Dale99]

So I've been looking for a blazer or burb for past month. Have found at 71 or 72 jimmy, the guy has said he will sell to me... Hes just has to find the title. It has been setting for approx 30 years. Tires have been stolen, some lights, bumper, etc.

Questions
1. Will 33inch tires, 4inch suspension, no body lift, still clear a normal garage door?

2. How wide will it be with 33X12.5 tires, on 15X10 rims with 4.25 back spacing? (fit on my trailer?)

3. The fender wells were cut out sometime in its life for large tires. On the rear, there is a panel that goes from the inner skin, to the outter skin. I am not seeing this on lmc's site/book. Is this part of the patch panels, or no?

4. It has manual steering. I would like to convert to power. On my dads 67 we had to heat the frame and beat it in for the larger box. I thought I read/heard somewhere that this was "fixed" on later models. Should the power box just bolt on up?

5. I have read on the site the larger tanks from the 73-91 blazer/burbs fit in fairly easy. I never did see, is the ohm reading for the gas gauge correct? Or does something need modded?
