Quick question for all of you. I have a guy coming by tomorrow to look at a header I am selling for a 22re. He has a 2wd truck and mine is from a 4wd truck. I know that there are differences between 2wd and 4wd headers and imagine it is due to clearance issues/length of the drivetrain. I also know that there are differences in how the tubing is routed that would also affect fit. Does anyone know how the 2wd vs 4wd headers differ?

Thanks in advance

 

The 2wd header will not fit a 4wd. It'll hit the bell housing and no amount of clearancing the header will allow it to fit.

I wasted 200+ on a header for a 2wd thinking all 22r stuff would fit.

 

This was the opposite problem, the guy has a 2wd and wanted to try to fit the 4wd. It looks like it wouldn't fit because of the stock crossmember on the 2wd. Oh well, I am sure someone else local will need it.
