All parts were purchased locally from www.rtbb.com.au - including the new centre ramp, which is a perfect fit and replaced the aged original. I didn't want to repair the old ramp, as the reproduction ramps offer great value and are constructed much better.
I agree, the NOS Williams ramps aren't worth it by a long shot if the repro ramps Greg keeps are available for the game. I've had these ramps from Greg for a few games - AFM and FH come to mind - huge improvements over the originals both in material and strength. My biggest regret with FH was I was given an original Williams NOS Steps ramp and used that - really looks like the poor cousin on the game.
I'll grab the old caliper and do a comparison. If the repro ramp for a particular title is availble, it is a small price to pay to ensure the game looks and plays 100%. The first thing I noticed on this title was the middle ramp shot was smooth.
Thanks for the kind words, guys - The game is going to a good home
