That. Polished or painted, the Explorer setup is very nice looking.
I love the March Performance stuff too, but not in a Bronco. And that's all due to the clearance issue already mentioned. Even the stock stuff only leaves, what? Maybe 3" between the radiator and the pump snout? What about after the A/C install? A little less even if you have to move the radiator back a tiny bit for better clearance of the condenser?
Which March kit are you looking at? Does it have a single or double belts? If double, I wouldn't even consider it, but if a single, did you look up the specs on it? I thought they used to have a chart showing dimensions from the engine to the front. If it's more than your stock setup is already, I'd say avoid it entirely.
There are several slick-city serp setups out there, but I'm pretty sure that in all of our searching over the last twenty years there is still nothing out there with the extra clearance, the solid mounting and the clean look (relatively) of the Explorer.
Get 'em while they're still out there!
