Hi Bret. I like your attitude
I picked up a really good 16GP4 from captainmoody a few weeks ago and another good one more recently. Actually very close to Barrington in Island Lake, IL.
They are shorter and 10 degrees steeper, but I hope to make one of them work. Plus my 16EP4 may have a smidgen of life left. I'd rather someone restore your whole set than see it parted out.
If you'd ever like some help getting your sets working just let me know - I'd be glad to help.
