Steve (Firebird) is a top fella that does great pads, he's very reliable so can only assume he's away at the moment or really busy with work as the pad making isn't his day job
I'm pretty certain he won't make any repro pads that might land him in hot water with breaching copyright particularly with some litigation happy companies out there
Too much risk of the BMX police
If GT Pads are what you;re after then Steve P's link would be the best place to go to for them
