Disc brake conversion

I still recommend changing everything over if you're going to do that, so you don't have to keep a parts list of what came from where. For example, on my '72, anything up front is '74 Dart/Valiant. Simple. It all fits and I don't run into issues with this part not working with that part.

It's not hard to change a control arm (and a good time to add some extra caster). What's your motivation to keep it?

Main reason to keep it is for ease of converting back to original (not that I'd want to but I'm spending buku dollars now for stuff that I never thought I'd want back) and cost as the uppers seem quite pricey, even IF you can find factory ones. Also the ease and less parts needed at this time. I've got a LOT to do.
