My '69 Camaro Restomod project

[Gruth5]

Hi All,
I'm new to the forum, not too sure how to navigate around yet. I've managed most of my modifications with the help of my son and friends. I'm in the process of installing front and rear Ridetech supension, that's the fun part. I'm sure the question of how to alter the rear seats to accomodate the chassisworks mini tubs, same as dse, has been asked several times, but a quick guide to the best step by step pictures would be helpful. Hoping to have the car on the ground soon and screamin around town. Thanks
