I hate for a mod to get lost in NOS. You are fine in the mods section as this would directly transfer to all the s-series. As long as we know yours is a Blazer, we are good. No confusion.IMAGE
Have you thought about relocating that control box? That is pretty easy to do.
That would allow you to keep the grilles crossbar intact.
Trimming the top of the winch mount face down a bit will help your cooling. Flush to the top of your bumper ends and dipping down to the fairlead roller in the center perhaps?
It will be neat to see it all done. What are you thinking about for a finish?
BTW, check out the fullsize bumpstops thread. You are going to need them with the added weight on the front.
