Clutch firewall flex

Has anyone dealt with this recently? Ive read a s-load of threads but most were several years old. I know ford no longer makes the kit. I emailed terrapin mfg but haven't got a reply yet. It still shifts just fine but I have to floor it to crank it and it does flex a bit.

Make your own kit... it's just some bracing right?

My Ranger had a cracked firewall by the clutch cylinder, and one of the previous owners welded some solid steel tubing across it. They didn't repair the crack itself but that firewall didn't budge one bit. Even with the super stiff clutch that someone put in (which I actually liked).

I made this with just a drill, grinder and vise.



Check your clutch pedal for wear too, mine looked like this so I had to push even farther.



My repair:

Well I just crawled out from under the dash. Large crack that opens up when the clutch is pressed. I jury rigged something that might buy me some time. Hopefully terrapin still makes these things

Chatted with him on FB a bit yesterday. He's open and seems like a great guy. Says turnaround is pretty quick these days. I got my order in.

Got it fixed. Turns out the pedal bracket was broken too. Feels like a new truck now.

Just fixed mine with the Terrapin bracket from Jason - works great. I decided to reduce cussing so I removed the seat and clutch/brake pedal bracket for easy access. The only surprise I had was when I yanked the steering column out, it broke loose at a sliding joint just above the steering box, instead of where I removed the bolt just above the U-joint. I thought I broke something at first, but it appears to be designed that way, probably to allow for movement between the frame and cab. The kit didn't fit precisely (nor did I expect it to), but with a little cold metal forming and reaming out some of the holes in the bracket, it is installed solidly and the clutch feels so smooth now!

Hi,
Wow!

I just replaced the clutch MC and the safety switch on the clutch rod.

I had noticed this upgrade but when I checked my 1989 F-150 it already had the Factory enforcer!

Jason at Terrapin is no longer making the reinforcement brackets. Anyone know of another source?

EDIT - Looks like Jeff's Bronco Graveyard has them for $85 - https://shop.broncograveyard.com/83-...8aAoUxEALw_wcB

My repair:

howdy! Anyway you can share dimensions/share your approach to fabbing that? $100 is too much to pay for a plate of 16 gauge. Thanks!
