Center Window Post deletion - your thoughts?

JAG. FYI, I have 1965 C337 and the wind shield was replaced a year before I bought it. It has the center support post and I don't see any problem with that. BUT A WORD OF CAUTION-please be sure to over size the holes in the wind shield to prevent cracks in the glass. The A&P and previous owner did not and there are two small cracks, that I had to repair, in the hole for the compass. I also see a benefit to having the post so the Compass and OAT gauge has something to mount to. I replaced the whiskey compass with a vertical card but I did have to drill an extra hole through the support and wind shield. By removing the old compass mount the extra hole was needed because the Vertical card compass had to be moved upward for clearance.

Bill,
Yes - thanks for the reminder on the drill size. I was planning to drill the holes 1/4" for the 3/16" screws (1/16" larger) - I think the general rule of thumb is to make the hole 30% larger. I too have the Vertical Compass with a nice mount, and that is a big reason I am sticking with the center strip as this (and the OAT) mounts so nice already and saves me having to make a new dash mount.

Thanks again for the feedback.
Jeff

JAG. Thanks for the reply. Hope yours comes out better than mine.

I went with vertical card compass mounted on glare shield.

Keeps everything nice and open,
