what kind did you use?
I got a set off of Ebay
http://www.ebay.com/itm/OBX-Performa...2a5fd7&vxp=mtr

but the problem I had was #1 header pipe was to close to the spark plug and would burn it causing a miss fire. so that's why I took it off and reworked it. not sure but looks like they might have fixed the problem.

when you say reworked....alil heat and a pursuader? giving more room?
i would prob wrap mine when installing them with marine exhaust wrap.
and as for snapping off, im running a 160 degree t-stat so it runs cold, and we have a trick in the marine field for keeping bolts from freezing in in high heat areas.
we use PTFE grease on all bolts

what are you two running for rear drive shafts?

Yes I'm running the XJ shaft in the rear and a modified stock front shaft. as far as the header I cut off #1 from the header flange and extended it with new header pipe I got from Summit racing rewelded it up and checked it for leaks. I also rapped the header with high temp racing header rap.

Haven't been on in a while but it sure looks good!

My swap has been coming along slowly. I bought those same headers and had the same issue. Ended up going with some off an astro van which will be ceramic coated. Only slight modification...

Same rad too but used an electric fan off and escort. Had my friend build a bracket to fit.



I found a shallower oil pan from a 2wd S10. I'll have to upload some pics off my phone with it in the Jeep.

My build in progress

I didnt need it, but wanted it. We've managed to tuck everything up there pretty good. I'm finishing off the front axle tomorrow, so I'll take some more detailed pics.
You can kind of see it here.

That was the original plan, but I ended up with a compressor.
