Hi Katie...Thank you for writing .I say K-Mart because they are cut rate.Like Wal-Mart etc...I just finished a 1961 Ford Falcon Ranchero that the owner bought and installed Shuck's junk ignition..He hired me to finish tuning etc...It left me stranded on the road because the cheap point set's rubbing block wore out in less than five miles!!!..The same goes for electronic parts..You buy the second rate stuff and you're asking for trouble...Let me know what you found..I might learn something...Regards...Al....
