I bought a procomp hei distributor from a vender at Cruisin Ms.Gulf Coast. It looks just like the MSD hei distributor, billet aluminum, red cap nice. I got it home and tried to install it into a l31 block and it will not fit without lots of force, its to tight. Then I pulled it out or pried it out. I rotated the rotor button and noticed the cam gear was wobbly. I pulled the gear and the shaft hole is misdrilled in the gear about .50 to one side. This appears to be a no exchange no refund product so save your money and by the real MSD if thats what your really wanting. I have been ripped.

 

Yeah that's made in china for you.

 

Counterfeit junk.
