ive been told that the tolerances or clearances which ever way you want to look at it are this,,, the QUICK TIMES are marginal as far as being square at the trans mounting plate, ?? also that now since they are powder coated,which is standard not an option,(i tried to get it un powder coated,,for a ton of B,S. was given to me as far as reasoning,,which isnt imoprtant,,,) as far as fitment QT may be the hot item,but i was told with the powder coating some imput shafts may not reach in to the roller bearing at the torque converter register hole in the crank,,grinding or milling of the trans mounting face may be required,,???????

any one with different information,,lets hear it,,thanks

There is simply no way in this universe that the thickness of powder coating a bell housing will cause the input shaft to back out of the pilot bearing! If this were the case you would only be engaging the pilot bearing by less than 10/1000", which is preposterous. My suspicion is that there was some misunderstanding. The only dimensions that are affected by powder coating to any great degree would be the i.d. of the bolt holes and the dowel pin holes. It is conceivable that is would be difficult to slide the bell onto the dowel pins if the coating was too thick, but I have not had any customers complain about this either. We have sold piles of these things for all kinds of Big3 applications and have a solid track record of happy customers. Just my two cents.
