Only use the fasteners provided by the new receiver OEM...if none or lost, replace
with Grade 8
DO NOT drill/hog out/grind/etc any portion of the TV's frame rail to fit the
new receiver. Worst place on any stressed member is the flanges, as they are
the main source of strength...the web to a lesser extent, but they too are in
the game (cross section of the 'C' channel frame rail)
After taking off the old receiver...clean, clean, clean the area down to OEM
paint/undercoating/etc
Apply a good coating of paint or whatever you choose. On BOTH mating surfaces
between the new receiver and TV frame
Torque the new fasteners to spec and on that...if the new receiver instructions
say to 're-use' the original fasteners...I'd get new Grade 8 fasteners. As
you do NOT know how they have weathered the years. Worst yet if you live in
an area where it snows and they use some sort of salts to de-ice
DO NOT drill/hog out/weld/etc on the new receiver cross tube. It is a torque
tube and any change in cross section will create a stress raiser that the OEM
did NOT design in or knew about
Other than that, not rocket science...just lots of work with a very heavy
hunk of metal...
