While building a 727 trans, I noticed the small hole in the face of the reaction shaft support was larger then any others I have seen.
So, I searched the internet and found a B&M modification that drills this hole to 9/64" and they call this a "Track Only Modification".
I checked the hole and it is 9/64".
My questions are, is this shaft stock from Chrysler like this on some models?
And is this OK to use on the street in a stock type transmission?
Or should I look for another reaction shaft support?
Any help would be appreciated.
Thank, Jeff
