Anyway, as a couple more parts come in, I have a couple of questions.
1) The ballcups of an original B2 are shorter in length than the black ballcups we buy today. Can someone who has an original tell me how long they are, as I would like to cut mine down to the proper size
2) For front tires, is there much difference between 6877 and 6878?
3) Apparently the original B2 chassis did not have holes for the anti roll bar. Can someone take a picture of the rear of their B2 chassis so I can compare it against the NIB chassis I found

Pics to follow as I make progress.
Thanks all!
