Hydraulic Clutch
As my Mk IV sits minus body and doors, etc., I am undertaking some corrective measures of things I really did not like while driving in gel coat.
I got to thinking (again) about replacing my clutch cable with a hydraulic unit. Just how much trouble is it to accomplish this?
Thanks.

Relatively easy with the body off. Assuming you're going to put a slave cylinder on the existing clutch arm versus a hydraulic throwout bearing that would require splitting the engine/bell housing. If you have a Wilwood pedal box, master cylinder bolts right in after removing the Factory Five cable mod. Mike Forte's setup is probably the most common.

If you're correcting my post, maybe didn't read it correctly. Or I wasn't clear. Agreed, no need to separate if using a slave cylinder on the clutch arm, which is how the Forte system works. Maybe too much information on my part. Just know some are looking at using a hydraulic TOB these days since they're quite common on DD's.

Sorry. Should have been clearer. Just the slave on arm type, not the bearing one.
On Forte's site, they only list the kit for T-600. I have a T-5.

I did it on a completed car. Not a big deal IF you are using a slave cylinder, not a hydraulic throwout bearing. It takes a little patience just because of the space, or lack thereof in the foot box. Under the car is easy.
There are several kits out there with various bracket designs and different slave setups. There are several slave cylinders out there, some with bad ratings. I did a lot of reading.
I bought a Wilwood M/C, and used the pushrod and slave cylinder from dazecars.com. I made my own bracket sort of like the dazecars one.
One thing with the new short version of the Wilwood M/C. It has a plastic cap that I didn't like for inlet. They also make a fitting. It is a special Wilwood piece with proprietary threads.
I changed my whole pedal box because the old offset cable clutch wrecked it. Compared to that, easy-peasy.

I have it on my T5, I got it from Forte. He has it for sure, just give him a call.
I’ve driven my own and another car with the FFR/wilwood cable setup and the hydraulic is WAY more enjoyable to drive.

Watch for interference between the slave cylinder bracket & the transmission webbing. My bracket required just a bit of clearancing (blue sharpie in the picture below). While my bracket was from Forte, it's probably best practice to check this no matter who makes the bracket.
Also, don't be surprised if you have to use a conventional bolt with washer under the head rather than a bolt with a flange. Sometimes the flange interferes with the body of the transmission such that you can't get the bolt through the bracket.
