1931 Splash Shield Installation

[fundytides]

I just had my 31 Roadster painted. I had all the "black" pieces (fenders, splash shields, etc) painted off the car. I am now beginning to re-assemble these parts to the car. There are 4 small carriage bolts that are intended to hold the back half of each of the splash shields to the frame. First question is should the bolts go in from the top or bottom? Second question is, am I going to have to lift the body several inches to get the bolt installed that is in the area of the "curtain pan" under the front seat? I can't seem to get my fingers up between the pan and the frame to install the bolt from the top and if I install it from the bottom, there is no way to get a wrench on the nut. I am hesitant to use a sling to lift the body because of the new paint. Any info/suggestions are appreciated
