Not sure which route to go with this, i just changed intake and carb o my 73 maverick. The original carb had a ball like end that the eccelarator connected to but the new carb is a holley carb that does not have that ball. Should i change the linkage or is there a peice that can be added to the holley card that will connect to the original linkage. i have looked in autozone and orieleys can anyone give any help.
