I just started a full resto on a 1969 numbers matching one owner triple black rs/ss convertable camaro. we were finishing the dismanteling today and found the P B & T stamps behind the ac box and under the r/s light relay and below the trim tag. of all the restorations weve done to date this is first for us. has any one else come acroos this. were shooting for a concorse restoration and would really appreciate any help during the process.
