Roger, while your at the NSRA show this weekend, find 'em on a car ask permission to measure 'em, snap some pics while your measuring 'em with a tape and save it, Doesn't look that hard a little bit of lathe work, aluminum rod and plastic dip and we will have you in good shape. I measured my hood props there one year, most fellas know exactly what we're going through and are willing to help. If it doesn't rain on Saturday and I see your car I will yell at you. Best of Luck Matthyj
