Weighted TC needed for 904 / 360 combo

I'm at a a bit of a loss as to where to find the correct TC for my application. Im swapping in a 360 and staying with my A904 tranny. The TC I was going to go with is no longer available from the website I was going thru: http://www.bulkpart.com/2/product/A904tcN/398.html "11 inch diameter, 122 toothe gear, 27 spline, 1.810 inch pilot, thin pads, 20:1 butterfly weight, high stall" 1977-up HIGH STALL FOR 360 ENGINE & TF-6
Notice: Converters do not qualify for free shipping!



They had a factory "high stall" with the butterfly weight that worked with my combo. It was at a decent price, but now no longer available. Can someone make a recommendation? My car is being built strictly for the street. Looking for a little extra performance, but realistically a factory high stall should be fine. (1970 Dart, 904 tranny, LA360)

Thanks
