Eric,
I sat in 1024 (with Dave's permission) and took measurements of his dash and cockpit. I also saw from the stands when he crashed it at PIR His front went over the rear of another car.
After the wreck, which turned out to be minimal, he jokingly said to me, "You want to buy some used GT40 parts?"
1024's a neat original that has a wider than normal flared rear clip. I remember seeing the number 1074 stamped on the rear clip. I suppose the 1024 clip (it being the type A) wouldn't handle wider tires so this flared one is used.
Have fun!
John
