I have a 68 roadrunner that I am putting together but did not take apart. I've restored and reinstalled the dash but have a bulb with no home. I think it is the 4 speed reverse indicator but I don't have one on the dash. On sites it has been mentioned that it is to be located one and half inch left of the ashtray just under the lower pad. I don't have a hole there. There is a hole lower down by the edge of the dash. I don't have the housing so can someone let me know if there should be a hole on the dash just under the lower pad or does this thing mount some other way? I did notice that company pamphlet show the reverse light as at the total bottom edge of the dash not up by the dashpad. Thanks.
