I'm new to this forum and this is my first post.
I'm currently putting my 1984 HPE back together and have read with interest previous posts on windscreens about which there seems to be some doubt and uncertainty at times.
I needed a new screen for my car and subsequently decided to get a new Pilkington screen through a local installer.
As part of their checking and rechecking to make sure it would be the correct screen, I received these 2 documents which I think will be useful others in the same position as me.
The photo document shows information regarding the rubber mounted screen, in this case, a bronze tinted one. The nine item schedule covers all Beta Coupe and HPE bonded screens.
The reference after the HT0508 product code gives the tint first followed by the top colour (if there is one) so the first screen has a blue tint with a blue top, the second is bronze without any sun strip, third is bronze with a blue top and the fourth is all clear.
Mine is the bottom one, green tint with green top.
The measurements shown are taken for both inside and outside measurements so you can see that 'LRB' at 1283mm is the screen's width at its widest point, towards the bottom, as measured across the outside of the screen following its curvature. The measurement 'chord', is the same measurement but on the inside taken as a tight straight line (not following the curvature of the glass).
From this schedule and the other info for the rubber mounted screen, you can see that the rubber mounted screens are 10mm smaller in width and 14mm smaller in height than bonded screens.
I hope this is of use to others trying to get to the bottom of this tricky subject.
