Hey I bought a pair for $40 from Will Zaraska which was an okay deal. The Zundspule ones in 1991/92 can be a problem but you can't see the date on that coil.
I ended up getting some Bremi's off a wrecker car because mine were mismatched.
I sold six for $5 each (not a misprint) to a guy on BF, $10 shipping just to get rid of them! (not including the boots)
It's good to have a spare in case one starts to short out!
