After the third attempt, we were finally happy with the steering column. We pierced the dash with a 1 1/4-inch, 0.120-wall tube and ran the 3/4-inch steering shaft through bronze bushings. The Grant Classic Model 5 steering wheel (PN 990) is attached to a Grant pinless quick release hub (PN 3024) that's welded to the steering shaft. The original designs would have resulted in a bent steering shaft the very first time we went all gorilla behind the wheel. This new column is much sturdier.
