They have a proper pigtail seating top and bottom, are tapered to help correct the spring seating angle and measure from ~11 to 17mm thick, so give a nominal 14mm lift.
I'm guessing at asking for 10 or 20 pairs, assuming they're not back on catalogue at Classic now, in which case I'll just post them back to Llanfyllin.
What's the level of interest, uf any?
