273 hipo,,,do you have the orignal bell housing ? if so that would be a 9 1/2 inch clutch,,,not sure if centerforce makes one for that,,,mcleod probably does,,
3 finger is orignal to mopar,,diaphram is said to engauge smoother,,,
ive run hays street and strip ( gold cover ) in an A body heavypedal pressure and you will have to brace the fire wall or it will flex.
i have been using a center force dual friction street strip set up for 12 years now,,i love it i also have a hyd set up on the pedal,,and it has a perfect pedal feel,,,
they say running a diaphgram type pressue plate to remove the over center spring,,on your clutch pedal,,,this is the large spring under the dash above the clutch pedal,,,i ran the spring for 10 years before readin this info,,i have since removed the spring,,,i see no difference,,
if some one is in need of a slightly used hays unit il look at it and see what it looks like and take pics,,,make an offer,,if it wil help your budjet out,
