[farmertom]

Tim,speeddawg.com or speed dawg shift knobs. iv'e recently replaced the original brown v8 ebossed shift knob in my '37 fordor cause the original knob way to small for my hand and dont car for shape of it either. imo the price was right i believe all the choices have a same size insert and you specify which insert you need.also geta washer which i did not use and a jam nut. Tom.
