I need to test the centering of my bellhousing
Does anyone have a dial indicator they could loan me
I would only need it long enough to test for centering then if needed I'll order the offset rowel pins and then set

You might try a local rental shop. If You go to Use-enco.com or ebay you might find that they are cheaper that you thought. What Bellhousing do You have? If its a Lakewood then the Hole is just Stamped out and not round anyway. If its a Mcleod then its Machined so poorly that the Indicator will jump around and You will find its not round either. If its a reproduction 621 thats CNC machined you will find its near perfect and won't need any offset Pins providing that Your Block hasn't been Aligned Bored. Do You have a Didital Caliper? Bolt something solid to the Flywheel that Pokes out of the Bellhousing an Inch or so away from the surface and just measure the distance in Four places as You turn the Engine.

Our local Auto Zone rents them out too. My only concern would be how accurate the are with all of the different folks using them.

I checked autozone and they dont have any dial indicators. also advance auto parts, oreillys, all of them are same story... no indicator
i guess i could goto harbor freight.
I am using factory bell housing from m-21 in theory it should all be lined up.. i just dont trust the build qualioty 40 years ago and i want to double check it.

Bummer..... do you have any friends that work in tool / die / machine shops? They would all have them and a few good mechanics (rite Joel) might keep a set handy too.
Maybe they would let you borrow them. Or, if you have the bellhousing out and available or can mock a template of the dial positions take it to them to be checked.

it arrived today.. i need some advice from the master.
i cant get the darn thing centered. i come back to the same reading at 0,90,180,270 everytime.. the problem is that they are consisently off centered. i can readjust the dial and make it less off centered, which usually makes tghe other axis more off center. is there a trick to getting the dial centered in the whole or just lots of trial and error.
Ben:
Have you ever looked at the Classic Chevy 5 speed install videos on their websitefor the TKO's. They have a good one on centering if I remember correctly.
LOL
