Finally got around to installing the Bill Ung saucer kit and figured I'd wax and clean the PF while I was at it. 1st time doing this since I've own the game. I noticed the rubber post sleeves next to the ramp entries are 2 different sizes. One is the slim version and the other is the thicker standard version like titan sells. Which one is correct?

Also, can any one fill me in on what is correct for washer placement on the ramps and wire forms?

Left & Right wire forms have a washer under the nyloc nuts down by the slings.
Left ramp has x2 washers under under the nyloc nuts, none between sling plastics and wireforms
Right ramp has washer under ramp on the tall post and a washer under the nyloc nut
Is this correct?

Thanks!
