Herb I cant remember how many times the car went on and off the frame. It gets easery each time.
As for a 4 post lift,unless you get the extra tall one and hang the body from the bottom of the lift you wont be able to use it to install the body because its a drive on style. A two post lift would be a better choice for installing bodies.
if you plan on doing the car yourself. John makes it sound easey to install the bumpers mounts I had a strugle with them.
Tools I used,Band saw,grinders,Sawzall,clamps,squares,lazer level,sheet metal brake,Migwelder,cutting tourch.Hole saws,multi tool.I have been cutting steel with a tourch and welding since a child,(grand father owned a salvage yard and my dad owned an escavating company) Now dont get me wrong I absolutely love my SR111 frame, But if you dont have axcess to the tools listed above,or you dont know some one able to make the brackets for you I would think twice prior to such an undertaking.We have 2 local mobile welders in our area who i could have hired to make the bumper brackets up for me,if I could have made them a template out of cardboard witch I could have done also
