Gotcha. Lots of options to eliminate then. Drill and tap the manifold directly? Little bit of mini die grinder work?
I'll post a picture when I get back to the shop this afternoon.
I just bought a 47 willys that's been built up by the prior owner. It's runnung 36" irocs like you talked about running. It's on 3/4 ton axles that are scout width. I like what you are doing and will be watching. I've only had my willy's 3 days now and am very excited to start playing with it. It's running a 22R Toyota for the engine.
Keep up the good work!!!
I found there are basically 3-4 people making the parking brake kit. For the Dana 300 you can go JB convertions, Parts Mike, AllPro offroad, or maybe an Advance Adapters HD rear output with a flange style DS.I'm sure there are multiple ways to go about making your own set up maybe using this and that and making some of your own stuff as needed. The key seems to be the upgraded rear out put housing. Following that is selecting a small enough disc that will work and a caliper to function. The mounting bracket appears to be the least difficult of all the components.
I really like JBconversions products. They aren't the cheapest but IMHO they put the effort into designing and machining quality stuff. If I built my own kit I would go with their rear output most likely.
link is to the upgrade... scroll down to fig 5 for the Pbrake pic. They don't sell the rest of the stuff but it looks similar to AllPros stuff in the pic?
PartsMike's kit uses AAs HD out kit. Its likely the least expensive route as a package. I had some difficult dealings with PM but he did try and rectify it as best he could. I'm just not sure I will deal with them again.But its worth looking into.
AllPro deals mostly with Yota stuff IIRC but I believe their kit is semi-universal?
You may want to sit down and price stuff out on your own using different components. I believe NWF (North West Fabworks) has a flange mount setup for the Danas as well?
One final bit of input on this from me. If I don't get to where I feel happy with the cost/work of this set up then my fallback position is to install a line lok. Its likely far cheaper and less work than the disc setup, not to mention it works even if a tire in in the air (or 3 tires!?!). Only real issue I have with it is that it is somewhat unconventional. Should I ever allow someone else to drive my jeep I would have to explain how to operate it. Not a huge deal but whatever, right?
I've got a Dana 18 transfer case though
I'm fairly sure I can fab something up. It would be really nice if I could make it use the factory e-brake handle on the dash I already have a flange type yoke on he rear output. I was planning on removing it for a regular style yoke, but I think I will keep it. For a flat fender I have a pretty long rear driveline. If I change to a CV rear driveshaft I will probably have to change the the rear output.
The wilwood mechanical spot caliper looks like it should work ok. I'm a little concerned about how small of a disc I can run. The smaller the better for my packaging problems.
The e-brake probably won't make the initial buildup, we will see how crunched for time I get.
Dang...Long day of being an idiot just got worse. lol! Sorry. IIRC, there is a seal built into your 18s output that keeps (sometimes) the fluid in the case and not in the drum brake? Maybe with some machinging skills you could alter one to work..? You could also look at motorcycle and scooter disc brakes as an option for a small disc? Maybe even use the handle bar lever to actuate?
