These headers WILL NOT fit the NNBS 4wd trucks.

See my other post in GMT900 section for full right up

 

What we've found so far for both our 1-3/4" and 1-7/8"

99-07 classic 2WD: perfect fit

99-07 classic 4WD/AWD: minor modification required

07+ NNBS 4-spd auto 2WD applications: perfect fit

07+ NNBS 4WD/AWD: WILL NOT FIT

 

So are your 1 7/8" headers on sale for $349?

 

Is not a perfect fit for 99-07 classic 2WD,I was installing the 1 7/8" today my friends 04 2WD and the passanger primaries is hitting the frame that it won't even bolt up to the head.

 

That's what you get for 350 bucks. I was possibly considering a set but not now after all the fittment issues I have read, even with 2wd apps

 

I get what you're saying but even if they were $50 I still expect a product to be as advertised "perfect fit".

 

I would pull them off and send them back and get a refund on them..

 

Minor modification required? that means they do not fit!

 

He still claims he makes these headers, so either he doesn't care that he makes a crappy product or he doesn't actually make them. Which one is it Jim?

 

By minor modification I assume bashing in a pipe so it wont touch the frame? So much for improved flow by adding long tube headers... just my .02
