72 duster Chrysler 3 speed

I run demolition derby double m its a pinto 2.3 against that Chrysler 3 speed I take 2nd and 3rd gear out they are indestructible I machine the front shaft down so the pinto bearing and clutch fork fits over the Chrysler and run a 3 puck tractor clutch I was using factory Ford Bell housings on the Chrysler but I seem to keep breaking them so made one up against a Dana 60 with 3.56 and now just trying to get my last Chrysler set up for this season
