I hear were you are coming from lads. I had a clock set for a K2 sitting on my desk, when a customer said , They look expensive.
Top yoke (unicorn) £200
Clock kit £120
Bolt kit, with D washers £26
Clock cushions £32
Chrome clock dishes £38
Clock chrome brackets £20
Pilot light set £26
Then you can add a couple of hundred labour.
I was a little shocked when i added it up.
The KO and K1's are cheaper because the Pilot light's are in with the clock kit.
