POL Front Disks Conversion w/Tubular A Arms

What wonderful experience today meeting a fellow Mopar enthusiasts on CL's who made me an offer I couldn't refuse. I was able to barter some cash and my radial arm saw for a brand new disk brake conversion kit with the tubular arms and a front stabilizer bar. Have you guys used the performanceonline.com kit SWBKS6274 with the control arms TCA-U6374ADC. Seems to have everything I need probably just need to get a new master cylinder. I will have disk brakes in the rear as well. Do you guys have a suggestion on a MC? Might want to go with a power disk MC over a manual MC. View attachment 1715130584

The kit appears to be a 73+ disk conversion using reproduced parts. Basically the same as factory for the 73+ disk cars, which is why the UCA's were included because the spindles use the large upper ball joint. The spindles, brakes, and hardware are likely the same as any of the other 73+ kits out there, it's not like there's dozens of manufacturers for those parts.

I don't think I've seen that particular set of UCA's before, but they look similar to the other non-adjustable tubular UCA's out there. It's unlikely that Performance Online is the manufacturer, so, they're also likely the same as another brand.

I don't want to be a downer but I have to mention that I've seen reports of SOME of those tubular A arms breaking. I don't know the manufacturer, hopefully it's not the one you have there. That looks like a nice kit, sorry can't comment on your MC question. Good luck!

I haven't heard of issues with ANY tubular UCA's since CAP was making tubular UCA's and LCA's. And they went out of business at least a decade ago. And those aren't CAP made arms.

So, where are these reports coming from? Do you have links or pictures?
