Unfortunately, some of these were made into Stndard and Extended Wheelbase Drilled blocks (#44 bit) with a raised wheel (it's hard to get good help). So, we have these standard and extended drilled blocks on clearance as well. They are selling for $1.95 each (normally $3.95). You can find these blocks at: www.maximum-velocity.com/inventory.htm#blocks
All blocks are under 5 ounces in weight, and are fully usable. As long as you prime and paint, they will work fine.
There is limited supply, so get them while they last.
