anyone done a hydro clutch conversion on a late 70s ford?

I think the pedal side looks pretty easy but the bellhousing side is a mystery.

1- is there a hydro throwout bearing available for the np435?

2- is there a factory external bellhousing for the np435 behind an M that I can hunt for in the wreckers?

3- any links to well done conversion appreciated.

I beleive you could probably use one like this on the right. It came off of a t-19 that was behind a diesel in a 84 f250.

If you want more pictures of the slave cylinder I can get them for you.

diesel bell has a different pattern from what I have read
I have read on other forums there was some depth differences in the 460 version from the M, I take it as unproven cause it wasnt on here subject to real scrutiny

thanks for the image

A bell for a 84+ 4 speed 460 should work. They use a linkage type clutch fork with a slave cylinder attached.

If you look at the stock setup for a small bolck hydro clutch bracket, its pretty easy to replicate. two of my buddies have done this for M bellhousings, to swap 400's into 90's trucks, however I have no pictures..

I did mine a bit different...
As I used a M bellhousing behind my 90' 460, which needed a 1/2" spacer to make the bellhousing fit.

When I made the spacer, I made a tab stick out from it long enough to later torch out for the slave bracket.

Here you can see it mounted up, I also welded part of the old small block slave bracket on to it, for the clip to hold on to.

pedal side seems to work out good using 80s ford f250 parts with a Russel AN-03 adapter

anyone tried these?
ID is a bit smaller then factory ford stuff but mounting looks easier
any P4x4 vendors for CNC stuff?

I believe the depth of that bell housing won't let the input shaft reach the pilot bearing on the 351M/400/335 series engine. I can get measurements to verify this in a day or 2 unless someone has the Al 84-up 460 bellhousing handy.
About the master cylinder: be sure you reinforce the firewall with a plate inside of where you mount it. This is important.
