Pic of front hitch on a gen 2
 

Recently picked up a winch for the blazer was looking at a few different ways to install it, most of them are universal permanent to the front. Also noticed that Curt makes a front hitch for the Blazer but can't seem to find a picture of a blazer with the front hitch installed, wondering if anyone has a pic of a front hitch on a second gen blazer with a body lift. Would like to keep winch so it can be moved front to back.

Being able to weld & fabricate I'd go to a wrecker & grab a Reese rear mount receiver & make it fit the front.
Look around online for custom bumpers & see how they design & mount them. Use that to fabricate/modify your own.
There are a few posts on here about front mounted receivers - great idea IMO, so usefull & you can store w/e you have mounted afterwords so it's out of the way.

thats what i did on my old 85, just cut it to barely fit in between the front frame rails and welded it in
