Jack's Comments:

Very accurate reproduction of the rear axle vent tube fitting. 

Application Notes:
1968-70 428 CJ, BOSS 429 This fitting was only used to vent the rear axle w/o a lock washer (kelly green paint code drip identified the location of the hole in the rear axle)
1968-70 200, 250, Std 302, 351W, 351C, BOSS 302, 390 This Fitting was used to vent the rear axle and secure the rear axle soft line bracket to the axle.

Lock Washer Notes:
1968-1969 6 cyl, Std 302, 351W assembly manuals show it also required a lock washer when used to hold the brake line strap
1970 6 cyl, Std 302, 351W, 351C assembly manuals show it holds the rear soft brake line to the axle and it doesn't use a lock washer
