73 E body front disc brakes conversion on A body. Where did I mess up?

Because it’s literally the same spindle as the 73+ A body? And he’s using slider calipers which is the same as 73+ A body? And SSBC is a flaming disaster?
Thanks for the info. I tried to ask as politely as possible. I didn't I know a lot about A Bodies, but I didn't know that. It has been about 20 years since I went with the SSBC brake kit. The kit was amazing back then. Has the company gone downhill since then?
It's the what if I need a replacement part issue. I am more comfortable knowing what's on the car and what fits. Granted it's a big learning curve for me especially when reading through the off topic threads.
I can see that.
