It does not have a Y Block in it but it is a related item. Anyone have an original? Trying to find out what ther original wheels where and if there is a source for parts for tese. Mine has simple coaster wagon type wheels on it and I am not sure it they are original or not. One is trashed and would like to go with correct wheels if mine are wrong. Mine is a '55 that has been sitting for years and I would like to get it running again before my grandaughters are too big to drive it.
