Is the one your thinking of? If so I bet this guy still has this one. Also....almost any set up you find is going to have 930 flanges...these things were builf for Busa powered buggys

$1000 FNR box

I tried looking for the name of that box but no luck
The guy that has/had that one told me the company went out of business....drop him a PM and find out...The only thing I dont like about that box or the rpm is the gear reduction built in

Well....In my opinion you dont mant much lower than a 4-4.5 to one final drive.....The rpm boxes start at 4.75:1 and go up to 10:1. So that leaves you runing basicly the same size front and rear sprocket....that equals a shorter chain and higher temps on your chain

with the transwerks box, you can easily change to a type one or two flange, it is just a clip that holds them on.
