Had the following trouble while installing a set of new bushes into the rear bearing housing / trunnion for a 1967 MKIII spitfire.
1) the lips on the shouldered washers (red arrow in the photo) was much thicker than the shoulder on the nylon bushing. If assembled as supplied, the inner/outer washer would have been deformed/squashed when installed and bolted to the uprights/trunnion.
2) the nylon bushing material is very poor - during my first installation attempt, one bushing deformed to ruin; the other cracked and snapped.
3) the o-ring seal provided is both too small to fit into place, and will easily snap if stretched.
The part number used was County QSK151S, roughly $5. When I re-ordered from another vendor for a much higher price, my assumption that I was getting a better product was proven wrong - I received the same part number, with the same issues. Shame on me for not asking questions.
I ended up using the bushings by grinding down the lip of the inner washer, and scrapped the o-ring. In retrospect, I probably could have scrapped the inner washer altogether. The nylon bushes did survive installation on my second attempt, using the highest degree of care to use even, gentle pressure while pressing them into place.
I'm not a Spitfire expert - maybe I missed something, but I thought this was worth posting in case a forum member is faced with a similar situation.
