The 2 kits I'm looking at are the universal Mcleod kit ($500ish) sold by brewers and a few other places and the American Powertrains ($670ish) kit. The A.P. kit uses a dowel rod to locate the slave cylinder and also uses their adjustable clutch master cylinder mount. It also comes with the shims to set the correct depth to the fingers.
I'd be curious to hear from anyone who has used either of these kits or if there are any other options out there.
TIA
