With about 30sec worth of grinding and a good vice they pop right into a duke 1.5 frame. So if you got some BROKE (DONT GO BUY NEW DUKE 1.5'S FOR THIS) dukes sitting in the corner of the fur shed. You can get the jaws from MTP for like $5 a pair. So just throwing that out there
So just to break this down a little more . I know for a fact about every trapper has a couple of messed up 1.5's sitting around. They got ran over,coyote pulled a jaw out,messed up jaw from the factory ,something. You have em but can't use em. And you like the wider off set jaw ( FOR WHAT EVER REASON ) but you don't wanna spend time welding and grinding to laminate and offset them or heck mabye you just plain can't, mabye you don't have a welder. And you dont wanna pay somone like me to do it. And you dont wanna go dropping $16 a pop for MB450's
As long as the frame is in decent shape ( heck even if it's been bowed out a bit you can hammer it back into shape) you can for go allll the welding and extra grinding of laminating and just drop $5 for a pair of 450 jaws . Only modification you need to do is grind the jaw tips a little . So $5 for a basically free trap at this point ,you can have a dandy little dry land trap. And before we start the whole "and actual MB450 is" WE ARE NOT TRYING TO BUILD A CHEAPER MB 450. Just putting that out there. On a side note even if we bought traps for this you can buy used duke 1.5's on the trap shed for less than half price pretty frequently. Even if we went and bout some $3 or $4 old dukes from a tail gater at a convention or off the trap shed bought the jaws and heck even new springs we still have less money in one of these than in a MB450. And where gonna get about the same effect TO A DEGREE.
Also about the only problem I've seen so far us the stock leavers on the duke don't want to ride completely up but seems like a little grinding will fix that.
