Little Shift Knobs
 

Hi, I saw a Web site today www.littleshiftknobs.com. They have some pretty cool shift knobs, however when ordering they ask for size, but not make or model. Is the size referring to the thread? Or the size of the actual knob? And has anyone ever order from them before that can provide some insight on quality and if they are a good company or not?

size looks like it refers to thread size...
