Please help with kart ID

[kwhmopar]

I picked this up over the weekend. The owner thinks it is an old Sears kart. I honestly haven't found a picture online just like it. The odd thing is it has no wings in the seat area. Very narrow front to rear. It has what at first looks like a live axle. Upon future inspection, I found only the right rear wheel is driven. The left rear wheel is actually a floater on a moving axle. The aluminum diamond plate was added by the seller. Any help identifying would be greatly appreciated. Thanks in advance. Kevin
