Would anyone here know the correct part number for a slant six flex plate? Having trouble locating one or a correct after market. Have tried several outlets and some don't know. don't go that far back, or wont look into sizing the diameter of the hole on the crank, and a jaded sales person or two as well. 1971 Plymouth Duster, 225, 3.7 liter, A 904 torque flight. I don't believe my plate is bad, but I would like to upgrade from stock if possible. You guys have always been very helpful, hope you can be now as well, much thanks

Thanks Reed, are any of these considered an upgrade? Or are they just OEM? Thanks again

Those all look like OEM to me, except the "universal replacement" ones. Given the prices are so similar, if you are really worried about it you coul opt for the "veavy duty engine" models with the bolt pattern correct for your application. ATP Z195, Z201, Pioneer FRA302 and FRA 413.

Just be sure to verify the bolt circle on th flex plate.

With rock auto, compare the prices with shipping............
(the cheaper one may become the most expensive)


and don't forget the rockauto discount (see the slanted network subforum)

Ok, I have a two and 1/8th crankshaft hole and a ten inch spread on my plate and converter, how do I verify the size? Don't see a phone for rockauto ?

Found some phone #s you could try.

They should get you close.

I noticed we always call it a flex plate, yet in my shop manual it is called a drive plate.
