Guys i need to now. What converter are you auto guys running for regular driving. The TO18b is impossible to find and im getting little to no input on what went in from the factory. One place is telling me that the TO40b fits but the bolt circle is 9.125" instead of the 9" that is the flex plate. Ive got this thing on the bench and almost ready to go (reprogram, raybestos cluches, etc) but as of right now i have no converter! Help!!
