Couldn't remember for sure, so I took a peek under the dash and it looks like I did indeed use my stock pushrod. It doesn't really "attach" per se, it just inserts into the m/c piston. Thats why i had to use the '72 unit because the recess in the piston had the same depth as my stocker. Go to the parts store with your old unit and pushrod then you'll be able to confirm it when you have the '72 m/c side by side with yours.
