I'm about to glue a set of 90-degree flanges to my header tank to capture the front edge of my glareshield.  I'd appreciate suggestions as to how much room to leave between the top of the flange and the bottom of the aft lip of the header tank -- this is the gap into which the glare shield gets shoved.  Of course, if I had an upholstered glare shield, I'd know the answer.  But I don't.  I just have a fiberglass dust cover from Lancair.
 
I was planning on leaving a 1/4 inch gap.  Does this sound about right?
 
Thanks in advance.
