How much do the 4 speed /6 bellhousings run, any available? I know there are some, friend and I looked and searched for one in early '80's, couldn't find one, wasn't sure then if they existed except for a truck-large flywheel. But as of lately, I understand they do exist and many of you forum members have vehicles witht them. When someone mentions 4-speed slant, I get closer to the computer screen.
