Sorry posted same picture twice !!!!
Took the car out for a blast without side screens and the top held fast thankfully !!!!
I found adjustments would be needed to the sidescreens by a small amount to lower them in the door fittings.in order to avoid catching the top.
I didn't want to modify the original sidescreens and found a pair of nearly new mohair covered screens that I can get modified....possibly a machine shop job .
I found these from an old project of mine..cockpit vents which should complete the Race look
To be continued...
