Hi Graham, I bought a set from Paul in 2018 for my twin. Very nice guy ro deal with and the kit fits very well.
(From my email)
The Twin C kit is: $58.00.
The (wet) clutch cover gasket:$15.28 The ET 140, for the C/D clutch cover requires a 'cut' gasket. I have one on hand, and the 'B' series ROUND gasket. I can ship the one ET140 I have, and order the cut gasket- 10 days- and sent to you as a back order when it arrives, or send you the 'B' round gasket. let me know.
timing side cover $14.42 The kit comes with an ET106 that is .032" thick. I also offer in .060" and .018", as well as the ,.032" which would you prefer?
The cost of the padded envelope for shipping- $2.29
Postage, approx. $23.50, which I will confirm @ post office.
