I JUST got the kits delivered to my door and little-A and I are putting them together to bring to DMS tonight. They are a strongly suggested $5 donation to CA for the wedge or block kits and $3 for the wheels and axels.
You need not use a kit but I felt having them here would increase/ease participation.
Each (car) kit includes:
4 wheels, 5 axels, wood block, basic instructions from the manufacture, a printout from Dms with all our rules.
