Installing Sub Frame Connectors?

Being on ramps would be no different than having the suspension loaded on the ground. Personally, I might let a body shop do it on their frame rack, if I was having them installed. You'd know for certain that it's square and level then.
 
I welded mine on myself using a set of ramps. It would have been alot easier if I would have had a lift but I like to do all the work on my car myself that I can. It dosen't matter how well you know a shop they don't love your car like you do.
 
So long as it's level I don't see any problem wit it:shrug: I'd do it, and if I ever get some I ''will'' do it myself on four ramps, whose to say that a shop is perfectly level:shrug:
