Front blade sight for "high" rear

I am dizzy from trying to find anything in Brownells.
I have an old school Micro rear (mounted high with no slide mods) on my 1911 and by my calculations using my standard load, my old fixed sight dimensions and the dimensions of my "new old" Micro rear, need something around .355 from top of slide to top of blade.
Can someone help me identify a part number from somewhere, for a stake-on front that is this tall or taller?
Thanks,
Ed

I think Sarco has what you're looking for:

I'd measure mine but I've already filed it a bit to reduce the height.

Perfect TJ.
Thanks friend.
