this site is pretty cool, although they don't carry the TRD lines. Although I have noticed that for the 94 corolla that TRD didn't make many parts.
As for which brand of short throw shifter to buy. It really doesn't matter as long at it is as least T-6 Aluminum or stainless. You can spend 34 bucks for an off brand one or 180 for a B&M shifter choice is yours.
I bought a short throw shifter off of ebay it cost me about 30 with shipping. I'll let you know if it was a waste or not. I figured I need to tear apart my console to replace my shifter bushing, so I might as well buy the short throw shifter because I want one anyway. Now I am just looking to improve handeling before making more power. After all what good is all the power in the world if you can't corner, but I digress
