Just tried doing a search but want to make sure before I place an order or hoping to find a good place to buy a flex plate for my 4r70w/351W combo. Turns out the flex plate I have now isn't going to work (it bolted right up, hopefully I didn't damage the trans!). I know I need the 164 tooth, 11 7/16 or 11.4" converter bolt circle with 28oz in balance (for C4?). Does anyone have a part# and or place to purchase at a decent price? Summit seemed a little high and I'm not even sure if it is the right one. Also looking for a dip stick for the trans as well. I know there are a few options out there, just hoping I can find something that fits well under the trans tunnel. Thanks everyone.

Got it in the mail today! I can't imagine this will be the last goof up of my build. Looks like the right one, right? Now to pull the engine and get this one in there...

Depends what motor you're putting it on. If it's a 5.0 the stock 50oz. Explorer f/p will work. If putting it on a pre '83 motor, you need a 28oz f/p with 11 1/2" converter hole spacing.

And all years for 351W are 28 oz.
