Helping a friend on his '68 and he recently bought a new steering wheel (not a Grant) and it came with some parts for the horn. My question concerns the order of assembly on everything in between the turnsignal switch and the new wheel. And, the brass button on the T/S switch....should it depress? Is a fairly large spring installed next? Again, it is an aftermarket wheel that came without instructions. There is a plastic horn "contact assembly" that appears to be installed after the large spring, and, this part is sandwiched up against the new hub assembly. Is this correct? Does this part move as the wheel is being turned? Does it come in contact with the T/S switch? A small, lightweight spring and plunger is also in the kit. Any help would be appreciated!
