It is rare, but does happen now and then. Try loosening the mounting bolts enough to allow the clutch housing assembly to move slightly. Start the engine and work the clutch pedal a few times, then shut off the engine and tighten the bolts. There should be enough play to recenter the clutch disc and allow the installation without offset pins. Unless the clutch or transmission has been replaced, it is hard to understand what caused your problem.

Its A 53 8ba when I put A dial indicator on the crank and turn the engine its running about .025 out of true with the bellhousing and i dont want to put uneven pressure on my transmission bearings A set of off set dowels would correct this and add life to my transmission

Dowel pins are not designed to hold anything is position. They are designed to set something in position. If you can install the transmission case in proper position and tighten the bolts, you're done. When you had stated .025" out of alignment, is that total indicator reading?

dandy32 I assume you replaced the clutch or something related to the engine ,transmission, removal and installation your pilot bearing lines up the engine and trans, and hold everything in Alignment so your trans bearing are ok if the pilot bearing is worn, you will get a slop in the Input shaft to the transmission, and more then likely when backing down , the gear shift lever will pop out of gear, how exactly did you measure the alignment , from bell housing to crankshaft ? I never heard of off set pins, in a bell housing or back of engine, hope this helps 37 TAGTOPMAN
