Dart 72 vs 73 susp dilemma

If I say I hate the u3 and later K member, I’d be lying but I don’t know what word is better. I hate it. I hate spool mounts.

Ok, got that rant off my chest. Yes, you could get disc brakes in 72, but I’m not sure you could with a /6. Maybe if it was ordered that way, or maybe you could. The fender tag will tell you the story.

As for the brakes...the 73 single piston caliper brakes IMO are a downgrade from the 72 four piston calipers. I’ve had both and I have the 73 stuff now and I prefer the 72 stuff.

All your performance brakes are multiple piston calipers. The K-H four piston calipers get a ton of hate, like the 67-72 K members, but that’s what I like. I’m converting my 73 to a 67-72 K member, but I, keeping the 73 brakes because I don’t want the small bolt circle.

What you have is fine, most of the stuff interchanges. If you do have the spool mount K member just make sure you order the 73 parts to rebuild the front end.
