5 years ago when I swapped a T-45 into my 95 TBird the McLeod internal hydraulic slave/throwout bearing was the only game in town. Now there's a new game. It's from Johns Mustang (JMC) in San Diego. Their set up uses an external hydraulic slave cylinder. You use a stock Mustang GT clutch fork & throwout bearing. The JMC package consists of a slave cylinder bracket that mounts to the outside of the tranny, a 7/8" slave cylinder with the pushrod & 3/4" master cylinder. The slave & pushrod push the clutch fork which disengages the clutch. I was surprised at what a difference it made. First of all the pedal effort was much lighter than with the McLeod unit. As you, who have the same set up I had, know the smallest master you can use is a 5/8". Even with that size the pedal effort is still a bit heavy even with the mildest clutches. If you get into heavier duty clutches the pedal effort gets worse. With my McLeod unit I would experience the clutch not completely disengaging from time to time, especially when stopped. I would have to put it in first before I got to a stop sign and then if I pulled it into neutral I would have to force it back into first. No one, not even McLeod, could figure out why. That problem has completely gone away. Not only is the pedal effort light but the clutch take up is smoother. It's an all around better driving experience. Another advantage is that if you have hydraulic issues you don't have to pull the tranny to fix it. The stock Mustang fork & throwout is basically trouble free so the only time you would have to drop the tranny is whan the clutch wears out.
From a cost standpoint the whole JMC system is about the same price as the McLeod unit by itself.
I will post some pictures soon.

This is the web site www.johnsmustangs.com. EM address [email protected] & phone 619-230-8866. You won't find my exact bracket on the site. I think I may have the only one at this point. They started out doing hydraulic conversions for 60s vintage Mustangs to go from mechanical to hydraulic systems. I found the best way to get in contact with John is by E mail. The hydraulic cylinders are made by another San Diego company called CNC, Inc (619-275-1663). I actually pieced my kit together. I used a slightly different master cylinder then comes with the JMC kit but it is still a CNC master (P/N 712-3/4) which is aluminum with a stainless sleeve. It has the same flange as the Wilwood so the adapter PapaJohn made will work. If you order it from CNC you will need to order it with a longer rod. I think it's 4". It has to have the same length as your current Wilwood. I got the slave & rod assembly from JMC as well as the bracket. You can pick up the clutch fork & throwout bearing from Cooper or 5 Star Ford. (stock Mustang GT).
Let me know if you get serious & I can help you out.

So, they DO make a bracket for the T-45, but it is not on the website?

All I would need is the bracket and slave cylinder. I already have everything else from my old conversion.

Either call them or send an EM asking for the T-45 bracket. What size is your master cylinder? It should be 3/4 for this application. JMC will recommend a 7/8 slave for that size master. You will also need the push rod from JMC. If you have a larger master let JMC know & they will give you the right size slave for your master.

When I talked to them last month they said the lead time for the T45 bracket is two weeks. They make them in batches.

I just bought my MCLEOD parts on Thursday, they are pretty rude over there if I must say, but I didn't really have many options. Then after reading all the overextending horror stories over on the AC Cobra website, got me shook now...

What is the web address of the AC Cobra web site?
I over extended my McLeod a couple of years ago when I was running a 3/4 master. Had to have it rebuilt. Once I got the 5/8 master I didn't have the problem anymore.
