................Easiest way is install the bell and trans and see if the holes lines up with the ball and bracket for the transmission side.................
A length of threaded rod from the frame side "hole" to the bell housing pivot can help verify the install. MP Chassis recommends the pivots be "straight across in any view".
IMO, The hole on the frame side location is a rather important item to have as the clutch pedal rod runs through the firewall. You don't want to run out of clearance for the rod travel.
