Ill take a set.
I've had first hand experience with ISC's Engineering and fabrication skills. not that impressed. I have their Swaybars the bar arms and front brackets are which are good, a bit heavy but the pillow ball bearings are way better than urethane and I hand to correct the bend the arms a bit to get fit as intended. the end links were cheap garbage and I could do a better job on the rear swaybar mounting brackets with a dull hacksaw. I think they freehanded them with a cutting torch and an angle grinder. I made my own end links with aluminum rod ends and aluminum hex bar stock. also re made the rear swaybar chassis mounts using 5/8" aluminum rod ends and re-made the brackets out of 1/4" aluminum dropping about a pond of weight.

i made a pair for bob and it looks like leafy is going to grab the "protos". if i even have the time, itll be a couple of weeks before i can make any more.
so i guess we will see if there is enough interest over the next few weeks to have a run made. if/when i get enough requests ill go ahead and start getting quotes from machine shops. if not, i will just make another pair for you glade when i get time.

now im just showing off
these are mine, leafys and bobs(pending) sleeves and spacers.
and this is the articulation. it will be a little less installed because of the knuckle housing- RUCA interfearence, but this is more than plenty for our application
im going to pack em with grease and stuff some o rings in there in an attempt to seal them.

im going to start a tentative list of interested members for a group buy. if we get to 12 or more ill start getting serious and submit a drawing to a few shops and get a price. i have no idea what this will cost, but im guessing at least $100 for a set of sleeves and spacers.

The rear sway bar 5/8 inch rod ends which weigh about a pound apiece were replaced with aluminum rod ends and hardware and the little plate brackets were also made out of aluminum.
Made my own Sway bar end links using 7/16” aluminum rod ends. Some brass tubing from the hardware store worked perfectly to make the Id fit perfectly with the stock size 10mm end fasteners at each end along with 10mm tapered washer rod end fastening hardware which fit nicely with the 7/16 rod ends. Jam nuts ant washers came from these guys

the setup wasn’t cheap but the aluminum Teflon rod ends have held up well for more than 5 years now. Front and rear swaybars pivot freely with almost no friction. By comparison the urethane swaybar bushings required with bent swaybars like Racing Beat Suck. My end links have lasted way longer than any others I have tried some whiteline ones I had prior basically wore out rattled and started to corrode within a few years. Got my rod ends for this here.

add me to the list - if you need someone to solidworks that up I can probably get that done (as others I'm sure).
If you want to run some prices through a cnc shop, check out these guys: Carter Machine & Design
I've sent a few work jobs his way and will certainly shoot straight on price / timing.

I'll give those guys a go to of we end up doing this. If they can beat my local guys prices then we all benefit.

also, every bearing manufacturer has install guidelines, including recommended bore and shaft sizes.
pg. 10. although the -T (ptfe lined) arnt listed and it says to call their engineering dept.
http://www.aurorabearing.com/pdf/technical-data.pdf
for a steel housing, the AIB-10 wants a 1.3113"-1.3119" bore, and im sure you can go tighter on the ptfe lined versions

Any reason to use a machined shoulder instead of snap rings on both sides? Emachineshop is quoting me $280 for 10x 12L14 steel sleeve with two grooves in approximately the correct dimensions. $38 for bearings here and $15 for spacers here comes out to ~$333 for enough for 5 cars, which comes out to about $67 per buyer. No idea how good these bearings are, but they appear to be made in the US by Midwest Control.
Is there any way to attach the sleeves other than welding? Being able to use aluminum instead of steel would cut the price of the sleeve in half.

the spacers need to be a specific length to match the width of the original bushing. i didnt do the math on those, but unless they are exact, theyd have to be cut, or more spacers added. im not a washer stacking kind of guy.
i will let people get their own bearings. not everybody is going to want $80 aurora, and not everybody is going to want crap QA1, and most may want something in between.
im going to use retaining compound to hold mine in. discussed earlier in the thread. i wanted to keep them steel for those that wanted to weld them in.
