hydraulic clutch kits

Has anyone here done a hydraulic clutch setup with hydraulic throw out bearing. I contacted American powertrains to see if they would do a kit. Looked around their website did not find the size I would need about 1.410 that is the ID of my throw out bearing. or 1 13/32 ID.  My transmission nose where the throw out bearing slides OD is about 1.408 Waiting for their response. 

 I second talking to Silver Sport. I also have a TKO in my 69 Rouge using there kit. I did substitute there throwout bearing for a Tilton. Also worked with Tilton on a smaller bore with longer stroke to reduce the pedal pressure. Installing the master would be a real pain in the rear with the engine in the car. 

Silver sport has a nice kit as others have said with the adapter specific to AMC to mate the master to the firewall.  The kit uses Wilwood masters.  I also changed out the master that came with the kit to a smaller bore.  The masters direct from Wilwood are reasonable if you wanted to change it out after the kits install (like under $70).  But suggest if you buy from SS you may want them to change it out from the kit to the smaller bore right upfront.  I believe the kit has a 3/4" bore and I went to 5/8" bore.  Frankly if I could find one I would go with a 1/2" bore.  At the 5/8" bore the pedal still is pretty hard to push (slightly less effort than a stock mechanical linkage and a B&B stock clutch) and doesn't have much feathering ability.  As others have said installing the master with the engine in the car is difficult but not impossible.  I did one with the engine out and one with it in.  Anyway If anyone knows of someone that can fabricate a 1/2" bore master with a Wilwood bolt pattern, please advise. 

I have installed hydraulic throw out bearings in 2 AMC's with T10's, a 70 AMX and a 66 American/401.  I used a Ram TO bearing in the AMX and a Mcleod hydraulic TO bearing in the American. the Ram bore was larger than the front bearing retainer, called Ram and talked with a tech, he suggested shimming, which I did, wrapping shim stock around the bearing retainer.  This worked fine as the TO bearing frame is static on the bearing retainer.  For the American I used the larger diameter AMC front bearing retainer and turned it down to fit the Mcleod TO bearing center bore.  When using a hydraulic TO bearing in an AMC remember that the depth of the bell/length of the input shaft is greater than a Ford or Chevy, so you will need more shims between the TO bearing and the front of the trans/retainer to set the depth.  The Mcleod TO bearing has a threaded adjustment for fine tuning.  I'm using a Mcleod bearing in a 75 Hornet race car that I'm building, however I'm using a Liberty Equalizer trans and have spec'ed the  front bearing retainer for the stock Mcleod TO bearing.  I used Wilwood master cylinders in all cases, Mcleod spec's a .75" bore minimum.  I fabbed mounts for the MC's and levers to connect to the clutch pedal to actuate.

Thanks much for all the response Fellow AMCers
