This one should be really interesting to watch, You know in the early days of Monster trucking, Grave Digger was a real truck, actually most trucks were real trucks. It wasn't till later that the owner of Bigfoot started using racing roll bar chassis that everyone followed.
its coming along great, but one comment about the frame, i dont think you can have the frame going this low in the center, thats should be actually one of highest points of the frame b/c thats a soft spot for those trucks.
EDIT: made a mistake, your frame looks correct, but the whole frame should sit up higher
Thanks for your comments guys.
The bottom of the frame was a bit low, so i've moved it up. The top is in the right position from most of the reference pics I have, it just looked low because of how low the bottom was.
I really think someone should make the old Grave Digger with all the rust, it looks really cool!
