Have missed the Body pins for easy access too, just because I like to check things over after a bit of racing..
Bought some cheap 1/0th scale Alloy Body pins for £2.80 and just screwed them in on the front and sides.
The rear body was harder. had to drill out the Tail posts and cut it thinner with a saw.
had to use 2 Body pins also on the rear.
Not sure how strong they'll be, I may glue them in place after a few test drives.
