Adapter Plate Thoughts & Questions

The input shaft of the transmission has only one ball bearing to hold it in place, beyond that there should be a needle bearing in the inner cone of the input shaft that centers the output shaft
Because the input shaft uses a ball bearing, it has no alignment value, it can move side to side too far to hold the clutch disc true when you depress the clutch

The input shaft has side loads that do require the pilot bearing

a spacer for the flywheel can be made but great attention must be paid to the flywheel bolts, they need to be the same hardness or better then stock and they must be an exact length for your spacer

the major hurdle is in the space required for the lower bolts in your adaptor plate, they overlap between the wide block and the narrow block and even if you got the bolt heads to fit, your plate may be over an inch thick, that would require at least a one inch spacer for the flywheel
with the extra depth of the flywheel spacer, you would need to space the starter motor towards the flywheel that given length

no,
that was the reason for the narrow block bellhousing, it was so you didn't have to pay for the wide block, plus you get to choose which trans you wanted

well if you want to build the flywheel spacer/coupler, I will build you one, so you dont get hurt but you gotta give me the proper thickness dimension and work out the adaptor plate you want

I guess the best thing you can do is build a plan and stick to it
perfect example is Jeff Ball's 510, he set his mind to it a long time ago and he hasnt let anything distract him into some long drawn out ,no win delema

dont worry about perfection, there aint a Hot Rod in the world that the builder wouldnt change SOMETHING if he had it to do over

finishing is the most important thing

Thanks for reminding me I still have a project to work on.

It's not that I set my mind to it, I just kinda found things that seem to work together. A lot of people need credit before any of my ideas could even be possible. Bill began this whole thing (to my knowledge) when he mad an adaptor to fit a stock DSM bellhousing to a Toyota transmission for some guy that wanted a Samurai or something with 3 transfer cases and a 4G63T engine.

My suggestion is to do exactly what you are doing Daviticus. Throw your ideas out there. Ask a ton of questions. Visit other project threads. Find out what you really want with this car. If it's already running, think about things you can change without much down time so that you can enjoy the car while it's being built. Suspension and brakes are always good things to start with. Also if you stick with abandoned project parts or used units, you can upgrade parts for cheap and sell them cheap if you change your mind or your needs change.
