2003 vintage s&s twin cam cases?

[HighLiner]

Obviously these are pre-T2 but what can anybody tell me about them?

I'm using a set of these.
You will need to use s&s external oil hose kit. Don't know if they can be drilled and tapped to use stock HD hose fittings.
Left side Timken bearing. Otherwise same same. Seem a bit beefier. I would use their cylinder dowels with the o-rings.
