Gregg - not to worry. The front should level right out with the spacers. Don't forget to re-use the stock rubber spring cushions or you'll be squeaked into nutso land. :{
Not sure what you are using kit wise but my (forget who, what etc) kit included grade 8 bolts & nuts to replace the stock ring w/bolts to hold the shock top mount (tower) and steel spacers.
The hardest part of the job was getting the springs back in. I set the frame on stands took off both front wheels once both sides were dissmantled I placed the spacer in and loosely installed new bolts minus the shock tower. I had to take the stock bottle jack and place it between the axle housing and frame to jack "down" the housing until I could "make" the spring go in. Then tighten everything up install the shock and go to the other side - repeat. If the top control arm gets close to the front of the pinch area metal (where the bolt goes through) don't worry it'll give about a 1/2" more if needed to fit the spring (mine did) you can simply flatten it back out w/BFH.
Oh as far as the space between "Bump Stops" (rubber blocks) and the axle I've heard the thickness of the top of a spray bomb (rattle can, whatever they call it in your neck of the woods) is OK if you have more after the spacers are installed - that would make sense right.
Have fun - it's about a 3 - 4 beer job depending on how hot or cold it is outside.
