looking for two driveshaft flanges that bolt to the transmission and the other end that bolts to the extension box. the set up i am using is a huber 1450 to a speedmaster #5 extension box

post some pics, I'm thinking about the same thoing.....

Is it a driveline style trans? Post a picture of the back of the trans. We make a billet flange, but you cannot convert a plug-in style.

yes its a driveline trans the part number listed on bam is 61218
