bigdog,
My 52 had stress cracks really bad around the booster mount holes.
My Uncle the PO ran it for a lotta yrs... and the stress worked on the fire wall, so that is why I made up a nice backing plate to distribute the pressure and firm things up.
Since ya doin the project now ...it is just cheap insurance for yrs. down the road an some one pulls out in front of ya and ya gotta STAND ON THE BRAKES you will have a nice FIRM mount.
Tim
