I was wondering, if anyone has ever converted their FB to a 5-bolt, more specifically the 5x 114.3 pattern. It's just so much more common, and so many more wheels made for it, that it would be something to think about. Hell, 2nd and 3rd gens use that pattern.

What would be involved in doing so? I know there are adapter kits out there, but I really couldn't find any. I'm just throwing the idea around, doubt if I'd do it though.

 

It'd be possible, like all is possible... But I took a close look at it, and then decided to forget it.
Indeed, you'd have a more common bolt pattern. But a lot of manufactures will custom drill their wheels to the old patterns. So unless you're planning on having different rims every year, the cost of custom-drilling is probable cheaper then the conversion.
Maybe it'd be easier to install 84-85 suspension. In the USA or Canada, that'd be GSL-SE, in Europe all 84-85 came with the uprated GSL-SE specs, less 13B engine (so 12A, but better suspension, brakes, uprated dash...)
It'd get you 4 lugs, but more common bolt pattern.

 

I actually have an SE....but the 5-bolt is still more common. Like I said, I was throwing it around.....

I wouldn't be changing rims every year anyway
