I am finally ready to do the finally assembly on my 94 and all thats left is header/cat/exhaust. I have been soaking the exhaust manifold nuts in PB blaster for a few weeks and got all but one off with no trouble at all. The one 14mm nut on the driver side behind the power steering pump I can't get to. I even bought a swivle socket extension and still no luck. I have removed the PS pump headshield which gave a little more room but still not enought (were talking mm's here guys). If you have put a header on your 1G NT let me know how you did it. Thanks.
