need help find 42hr trans

I replaced my 46RH in my 1994 ram 250 conversion van that went bad with a 42RH from a 1989 ram 1500 van. Both had 5.2 engines but my engine has crank ignition on the back of the block, so i had to notch the top of the bell housing to clear the crank sensor, i used a kack saw. The 42RH converter bolted right to my crank trigger type round flex plate (i didn't know that till i tried). The 42RH tranny lines are smaller type. but i use the rubber tranny hose to join them to my lines. check out (ete reman.com 42RH) for some info on this tranny, also its a 4 speed automatic with tail shaft like the 46RH and 3 prong. plug in for the lock up converter. hope this helps.-Jimmy
