Rear shock mounting hardware

Is the car modified so that you cant put the original studs back in through the trunk, and get a new spring mounting plate for the axle?
Or take the existing studs to a machine shop & have them turned down to original size?
RogerRamRod,

Well I would like to use the shocks I have and I do not think they will work with original hardware, not sure. Additionally, I do not believe they are repop the upper studs yet. Do you by chance know the dimensions of the original upper/lower mounting studs?
