Can anyone think of any SVA related issues with making a perspex dash and mounting the clocks behind it to avoid radius problems?

does it affect the readings...

in sunshine??

glitter???

reflectation??

by night??

Tks

No SVA issues at all, every modern tin-top seems to put all their dials/warning lights behind perspex/polycarbonate.
As tks implies you may want to make some kind of hood to stop the sun making it unreadable.

...and you'll still need to radius the bottom

I thought about just not having a dash at all and mounting my bike clocks on a bracket, and the switches on a small panel.

I'm not sure what the implications would be in terms of what would be considered to be the dash and what could be simply trimmed with edge trim.
