    Alright, we're back at now. Just wanna throw a couple of questions out to get me headed in the right direction. With the new YJ brake booster, i know i need to re-enforce the firewall, will a piece of 1/8" mild steel about 12"x17" big strong enough to keep the firewall from flexing? Also, just looking ahead a little bit, anyone out there us one of those EZ Wire kit? If so, what do you think of them? How's the quality? Any problems with them? Thanks guys!

    I use 3/16, but the surface area has alot to do with it to help with the flex. EZ Wire is great, used a lot of them and highly recomended here too.

    Thanks warloch. I made the plate about as big as i could fit under there so i can attach it as close as i can to where the firewall rolls into the cowl. Hopefully it will be strong enough, we'll find out tomorrow!! I'm thinking i'm gonna run an EZ wire, painless is a little to pricey.

    EZ is the same as the Painless (at least that is what I found several years ago with them side by side). I have installed 4 sets and have another 3 sitting here with projects assigned to them... I also like thier Dolphin Gauges

    Great job. I was wandering how you are planning on running the clutch. I see that you are upgrading to a hydro clutch would love to see the mount on it?

    As far as the clutch goes, I started with a slave cylinder and bracket that came from Novak. Maybe someone else can help out a little in this department because mine is not fully finished yet. It seems like the slave cylinder is going to be in the way, or very close to being in the way when i run my exhaust pipe. What have the rest of you guys done about this? I really don't want to run headers if i don't have to.

    The next part is just a 3/4" master cylinder made by wilwood that i got from summit. Then i hooked it up to an existing hole in the YJ brake pedal assembly with a 5/16 hiem joint. I'll get some pictures of that soon. The rest of the plan is to run 3/16" hard line down the firewall to the frame and from there use AN-3 stainless steel braided line to the slave cylinder.

    I went ahead and built my plate for the firewall out or 1/8" mild steel, but made it as large as i could fit to try and spread the load out to as much of the firewall as possible. I made a cardboard template and transfer it to the steel plate then cut it out with the plasma. After getting it to fit where i was happy, i coated the back side with a weldable primer from eastwood to try and prevent rust between the two plates.

    Here's what it looked like after first welding it in. I took my time and welded slowly to try and prevent warping the firewall.

    Then, after filling some unwanted holes, and then drilling new holes for the master and clutch cylinder, this is the final look.

    A few other misc. things i'm now working on. I was not too happy with the placement of the return line fitting placement in the power steering pump, as i would have had to run the return line over the top of the pump. So after some checking at NAPA auto parts, we found a pump off a 1972 chevelle routed the return line down under the bottom side of the pump. It hasn't showed up yet, so i'll let you know how it works out when i get it. Also 2 of the 6 flange mounting bolts were stripped on my original hubs, and after talking to ryan the jeep guy, i decided to upgrade to the newer style hubs and bearings. Those just showed up so i will be re-doing the front hubs soon, for the last time, i hope. Thanks for watching! We'll update when we get more!

    Yep, I had the same issue with my Novak clutch cyl.



    This is with a Chevy Vortec 4.3, it looks like your setup may have a bit more clearance.

    The Buick can utilize a forward dumping exhaust manifold on the driver side, I seem to remember seeing that recently on here.............Posimoto maybe??

    Lookin good so far.

    Regarding your manifold to slave cylinder issue...heres how I did mine. This was a buick 225 btw..I cut the flange off at the bottom of the manifold where it hooks to the pipe. I then ground both edges flat and had the flange rewelded to the manifold at a more favorable angle. It worked perfectly for my application and was a cheap mod
