I'm wondering if anyone could possibly help me trace the early history of an imsa 240z we have recently imported to the UK from America. We have photos from the car number 90 (attached). The earliest history we have is an old SCCA log book (attached), from about 1982/83 i think (hard to read the writing) owned then by Wally ?? Was this Walt Maas? We are in the process of rebuilding the car and have found a lot of traces of yellow paint on the roof area and as we would like to restore the car back to how it originally raced in the early 70’s we are keen to find out its very early history. Can anyone help? Thanks
