Non-Patrol extendable towing mirrors

[jff45]

Would it be worth taking a mirror off and tracing out a template also marking mount holes to take with you to the US?

I thought I'd just take pics and measurements of the GU triangle and get what appears to be the closest
If I'm going to make my own adaptor plate I'll probably have grind the new one a bit anyway.
The important part will probably be the angle at which it leans in or out because they're not a precise vertical fit.
