Default Bellhouse alignment

I am in the process of installing a 5 speed in my 72 it is a body off so I have access from the top on a bare frame. I decided to check alignment with a Browell alignment checking tool with the stock dowel pins installed. The Browell tool installs on the crank and projects outside of the bell housing and has a ring the slides on, if the ring fits inside of the bell housing opening the bell housing is aligned. To my surprise it was perfectly aligned so I didn

't have to use off set dowel pins or use a dial indicator.

I am going to install a TKX on my car soon and was curious if using this tool compared to dial indicator will meet Tremecs warranty requirements since no measurements are generated?

My transmission was out of warranty so it didn't matter. I struggled using an indicator only to find out I didn't need offset dowel pins.

I like that tool.
I also fought with the dial indicator method.
Where did you get it? Part number?
Thx in advance.

Here is their web site https://www.browellbellhousing.com/components.html# I thought I purchased it from Summit but they don't show they have it. It is kind of a one time use after I get the transmission in I may sell it.

That is pretty slick, do you remember how much it cost? (I don't feel like calling them)

If your fancy new tool says "NO GO", you still need to do this anyway. The magnetic base and dial indicator came from Harbour Freight so it does not break the bank.

These dial indicator setups are useful for other tasks like degreeing a cam or checking rotor runout etc. I just dont like buying "single tasker" type tools.

,, For warranty purposes, I definitely would use the dial indicator, and photos to show that you are within specified tolerance.
,, To avoid premature ware on the TKX get it right on the money. You'll be glad you did

That is a slick tool, and I would probably use it.
But, I've often thought that the offset bell housing is generally a non problem.
Did GM ever have problems with this from the factory??

GM never had a problem because factory used ball bearings on the input shaft. Slight misalignment not a problem. Most all of the newer trans have roller bearings on the input. Misalignment can be a big problem.

.
Yes, exactly correct. Not really too difficult to do, but extremely necessary to make the new transmission have a long and trouble free life.

That looks like it could be tough to manage while Engine/bell are still in the car. True, or no?

Not that bad. It is easier the way i did it if you already have everything apart.

Drop the trans and add the bell. Take the measurements then pound the dowells out of the block (little tricky) and replace them with those fancy Lakewood offset pins. Done.

I can't see how it would work. There is no way to know if the tool is centered on the crank. 2 loose slotted crank bolts opposite each other? No rotation? No measurements? .......No warranty.
