I'm just about putting sound deadening pads in. Gonna fit 2 in each wall 4 on the roof and 1 in each back door. Then i will put in heat insulation before the carpeted wood panels and storage boxes go in. My Bull Terrier wil have a blast in the back.
Also have the Saab back seat's backrests, took out the armrest so they will fit between my subwoofers, they will be fitted back to back with the front seats (easy removable with the original clamps) for day trips or meetings, so i can kick back and watch a movie or so on the screen i'm gonna fit in the roof directly behind the back doors.
And i'm thinking of a double floor to house a picknick table. Got that idea from my parent's old Simca Tourist en the Ghia Seeka.
