If i find a decent backglass someday (no rush), i'll grab one for sure.
The panhead screws were from bunnings.
They're "6g x 12mm" woodscrews (there's 4g/6g/8g/10g in various lengths)
I used the "6g x38mm" for mounting plastic posts in the lane guides too.
Some posts needed "8g x 45mm" because i couldnt find 6g x 45mm.
(The 8g size will need a bit of threading initially into the plastic posts).
I then added a 1/8" washer to make it appear skirted like the originals.
The washer has to very slightly screw onto the 6g thread, which is great, coz it seems to hold the washer central and not let it droop off to one side.
Oh yeh, be aware that these 'g' screws are available in small plastic packs of 10-20, then larger plastic packs of 100, and also in plastic bags with a paper label-top.
The different types have different chrome appearances.
The ones i preferred were in the plastic bags, they seemed to be a little more blue'er and chromelike, the plastic pack ones seemed a little frosty and even brownish in appearance (cheaper processing?)
They're all ZINC plated, but their appearance differs between packs drastically !
Hope this helps.
