well, after I got the sides square and the hieght right, I had drilled the front side first and now I gotta drill the back/ trans side

The first thing I did was to index and drill the three guide pins

After the guide pins were drilled the bolt holes can be put in

here is the first test fit, checking index of the engine/bellhousing guides

now its tear down the jig, remount to the rotary table upside down and dress the clamping hole while adjusting the hole depth

now its time to drill out the clutch fork hole, i made this guide so I could accuratly get the hole lined up each time in the same exact place

The next step was to assemble the front cover of the R 154 and bolt it up to the new housing, I have to check the hieght of the clutch fork pivot ball and the proper location for function

Now I can assemble the flywheel clutch assembly and test the clearances between the flywheel and the belhousing

I fitted the guide pins in the bellhousing and placed the adaptor for the R 154 on all three guides, I used a dummy input shaft I made to center the input shaft to the clutch disc and the front bearing hole in the transmission case after it passes all the way through the bellhousing and the adaptor

Now that is a decent , strong, and safe housing/ adaptor setup that looks and fits right.

You might ask why I didnt just make a complete different bell housing? well the answer will be the final step in the plans. The input shaft is so much longer and the throw out bearing collar had to be adjusted for length, I will show you how I decided to create the proper throw out collar in the next set of pic's
