4-Door bull bar?
 

I have a '00 4-door Blazer LS 4x4 and I've been trying to find a bull bar for months to fit it with no luck. I find them for 2-door models no problem, but when it comes to the 4-door, I'm having absolutely no luck. Any ideas where i can get one to fit? Or, is this a situation that I'm going to have to buy something and "make it fit?" Also, i'm looking for a trailer hitch that will allow me to keep my under-body spare where it is. Thanks for any ideas!

Two door and four door are the same frame in the front. A two door one should bolt right up.

A 2dr should fit a 4dr as long as you don't get one for a zr2. The zr2s as wider in the front as far as the frame goes IIRC.

Bull bars (on the front) are the same for any non zr2 s-series

You not meaning nerf bars are you? They are different for the models.

Actually the frame in the front even on a ZR2 is the same. Its different where the suspension mounts to it.

I literally just ordered this for my blazer ~30 minutes ago. They look decent to me, and its by far the best price I've found while shopping for them on the interwebs. When I get it in I'll post some pics.

As far as a hitch, I installed this one about a week and a half ago. I didn't have to move to spare at all. It's actually gone down in price since I ordered it, and its free shipping too since its from amazon and it's over $25. It's also one of the only hitches that I found that is rated for the same towing weight as my blazer is, which is 5,000 lbs. Took me about an hour to install.

I really hope you're doing a write-up for your engine replacement project. Also, how'd you do the wiring for those lights on top of your ZR2?
