i have no personal experience with the conversion, but you hit on some key points i was thinking about before posting. one you didn't mention that is sticking out to me is what benefit will you get out of converting a 9'' to ff besides retaining a bolt pattern and keeping a tire from falling off when you bust an axle? which to me seems like a silly way to piss away money to patch a problem like needing to upgrade to 1 tons because you've obviously outgrown the limits of 1/2 tons. i just can't see dicking around with 9'' axles nowadays because if they aren't cutting it how is the d44(assuming it's a d44) front keeping up without issues?I have done one. In a nut shell I just cut the spindles off of a rear 30spl d60 (80' dodge i think), chucked up the spindles in a lathe, cleaned em up. Bored the center to fit a 35spline shaft. Chopped the ends of the 9"off. I drilled the hubs for 8x170mm to accept late model ford super duty disc brakes in order to match the front 9". Welded it all together. Made a caliper bracket. Then ordered custom length yukon axles from randys.
fyi-I'm a "certified" welder and have access to manual mills and lathes
All in all it took a ton of time and I spent way more money than I thought I would.
For me it was more of a personal challenge, because I had never done something like that before.
The price of that kit is low enough I would go that route. Or get pick up a junk yard rear thats all ready ff
I don't mean to sound like a dick. I just want to make sure you know your making a big commitment, and also you must be confident enough in your skills, before you get to serious.
If your really sure you want detailed info with photos. You may be able to persuade me to get a red star. I have a tube eb build that I think would be well excepted here.
I dont see it listed on that page, but most likely wont find a "truck/4x4" bolt pattern from them or others like them, as most are for roundy round applications that use car type bolt patterns. probly limited to 31 spline as well.Anyone done a full float to their 9"? If so what components did you use, and do you know of any write ups?
