Gentlemen, just converted my standard shift 57 tbird to a fordomatic tranny. Question is what linkage is required for this setup. I have a 312 inch y-block with a holley 390 cfm 4-barrel. I have the correct fordomatic bellcrank but not sure about the rest. Talked to a Holley rep and he said I needed some  kickdown hardware which I have ordered from Holley. P/N 20-91 and P/N 20-41.  I do have the kickdown rod from the bellcrank to the transmission. I do not have the dashpot---would like to know if I need that part, as I'm not sure what that device does. Any and all comments will be greatly appreciated  Thanks,  Dick Palmer
