lift kits and new body mount kit?

We're in the process of restoring our 75 cj5. In the process of removing the tub to prep and paint it. We're going to be using new body mount bolts when we replace the tub. When we bought the jeep, I understand that it has a 3" lift kit. My question is, do we need to be concerned about bolt length, etc. with the lift kit when buying the new body mount kit. And should be go with stainless or zinc? Thanks for the help.

 

Is it a suspension lift or body lift?

If it is a body Lift, I say cataog all the bolt sizes you have and then get them in Stainless.

If you are talking about the leafspring bolts I would get them in Grade 8.
