rear disc conversion issues

Yeah, apparently these are modeled after 1979 Cadilac El Dorado rear calipers. Bleed screws and banjo bolts are annoyingly metric.

I forgot to mention in my initial post that I did replace all the flex lines with braided stainless when I put this kit on as well as a new stainless rear axle line.

I'm thinking there must be a residual pressure valve in the mc behind the tube seats as the service manual shows. That's item #1 on the list to check in the morning.

Thanks.
