54 Merc quarter panel spears

Anyone know how the 3 spears are held on? And if the backside has to be accessed, do you get at them through the wheelwell or from inside the car?

 

btw, the reason im asking is because I dont have the car in front of me but I will be removing them and I want to know what tools to bring.

 

They have studs on the back and if they're on a 4 door you'll have to take the back door panel off and go in through there, otherwise on a 2 door you'll have to pull the back seat out and the rear panels and get them from there. I want to say they have either a 3/8" or 7/16" nut on them, bring deep wells to get over the studs. You'll also want a door handle clip remover tool and a phillips screwdriver to get the panels off.

 

yeah its a 2 door. Looks like its gonna be alot of fun playing in a snowbank haha.

Thanks for the help.
