Re: '67-'72 Power Brake Booster Bracket With Hydraulic Clutch Conversion

I used -4 AN 36" AFCO hose (pn 40280) with a -3AN to -4 AN fitting, but could've used a few more inches of hose. The 36" hose worked, but just barely. Another 12" would give you more options to route the hose in a neater fashion.

For my 2006 NV3500 I used the stock slave clutch cylinder out of a 2006 Silverado 1500 4.3L, Rockauto part number 360128.

Did I send you a .700" bore clutch master with your kit? If so, does the clutch disengage enough?

Yes you sent me a 0.700 bore Wilwood master cylinder. It moves the slave far enough to fully disengage a brand new clutch pressure plate and flywheel.

Thanks John, your entire kit is very nicely designed and produced. Please excuse the tape on the last picture I lost one of the c-clips.

Re: '67-'72 Power Brake Booster Bracket With Hydraulic Clutch Conversion

Where would I be able to find a new tailshaft housing for my 4x4 nv3500 to make it a 2wd?

There should have been an extra e-clip in your hardware bag

Have you checked a transmission shop? The trans is going to have to be completely torn down to change it to a 2wd. It might be cheaper to just find a 2wd NV3500. You might inquire on the cost to change yours over to 2wd.

Re: '67-'72 Power Brake Booster Bracket With Hydraulic Clutch Conversion

Glad I found this thread. I was scrolling down looking for a clutch pedal to convert a '69 cab to manual. The cab will be going on an '89 C30 with hydro boost brakes and external slave. I was already imagineering a way to get this mismatch to work. Seems you've already done that..
The '89 already has a new clutch master on it. Any way that would work with your kit ?
Thanks

Re: '67-'72 Power Brake Booster Bracket With Hydraulic Clutch Conversion

Sorry for the delay in replying

All of my hydraulic clutch conversions are designed to run a Wilwood or similar clutch master. I do not think a '89 C30 clutch master is compatible.
