Im 55, Been climbing phone poles for over 20 years, am disabled now, got hit in the rear. HARD to get motivated on my LAST build! almost done, not quite. just got the rest of the chrome and aluminum back from shop, have been stalling putting it on. Got new heads rebuilt 714 casting heads, still on the shop floor, got a 8.75 rear end same place as heads! I need to get motivated! MT
