You can have my Your-Fit .335 and .370 the predecessor plus the corresponding heads and shafts or just the Your-Fit connectors and heads....damn cheap and I mean cheap.....almost FGI cheap bastage cheap. I have lots of Wishon heads and shafts. If you e-mail foregolfcustomclubs at gmail.com I will e-mail you a list of connectors, heads plus shafts if you want the shafts. I won't refuse any semi-reasonable offer.
BTW....in the heads there are some great ones I need to look thru what I have but off the top of my head 2 919THI heads, irons 771CSI, 575MMC, 560MC, 979SS, 755PC plus others. I will dig everything out if you are interested.
