48-54 chevy bel air..what step notch?

what step notch do you guys use? anyone use a Welder Series notch? thanx for any info. its going in a 1951 bel air.. i want to lay frame

 

I used the Gambinos step notch it worked out perfect

 

cool cool thanx for the help after more looking and talking to a few members Gambino Kustoms looks like the best notch built for a 48-54. thanx again.
