zero rate leaf spring
I'm not sure who was asking about it, but there was a thread just the other day about drilling front leafs to move the axle. Would you consider these "lift blocks", in other words, would they be nay for the front end? http://www.offroaddesign.com/catalog/Zero%20Rates.htm

Thats what I figured. They're only an inch tall, so they're really not going to constitute any axle wrap. Plus they bolt into the spring pack, so I thought they would be good. 1.5 inches seems to be the safety limit on them.

I used the same ones on the rear of my 79 250 when I did the shackle flip to move the axle back 1.5"s, back to its original position (check my gallery for pics).
I wouldn't fear using them on the front end, they're bolted to the spring pack, no worries about loosing them, and they're short enough that they shouldn't add to spring wrap.

I used a plum bob on the wheel well to mark the axle before I did the swap and after, and the shackle flip will move the axle ahead aprrox. 1.5". Zero rate's took care of that

Not that I've noticed. You could actually leave the axle 1.5"s ahead of stock, I don't think that there would be and clearance issues. I did it the zero rates for the 1" of lift and (hold on 
) better appearance of having the axle centered in the wheel well.

Look close at the pic of the blocks. There are 3 holes one recessed center, 1 recessed 1" (on the opposite side) and 1 recessed 1.5" (on the same as the 1" offset) You run the spring bolt through and put the nut in the recess with a little extra sticking out as a locator pin. Easy enough...
