hi Magnum, sorry for my english im not really good at it ! Nice project with your diesel engine swap!
I have done some mods also to my response 1997, using the famous suzuki g10 engine 1 liter. As clutching i use polaris snowmobile clutch and team secondary (with the good bore for the transmission). A machinist made me an adapter to bolt on the flywheel and taper bore for the clutch.
good things with polaris clutch is aftermarket parts you can get to fine tune for low rpm shift. and for backshifting the secondary quick to have tons of torque when you turn.
here is my project page if you want some informations of parts i used in clutch and secondary :
