It would be very interesting to see what the average age is of those who have the skill of drilling and tapping......
I'm 45, , and grew up with my older brothers building real Hot Rods ( unlike the annoying things that swarm around today , that beg to be swatted with a rolled up newspaper) I
was exposed to many mechanical tricks , however this wasnt one of them.
Hopefully my 35 year old A-4 wont require this procedure any time soon.......
