Instructions on replacement of Exhaust Manifold
Simple remove heat shields, removed four bolts on each set(therefore there are 8bolts total) remove exhaust manifold clean manifold replace with new gaskets.

Don't sweat it if you break a bolt in the manifold... just let me know and I'll walk you threw it. .. By the way its a good time to use some dressing on the manifold pipes.

Do you know what the common problems with the 1981
Biggest problem is neutral safety switch. When it goes you have no crank no start. A pain to get too have to remove driver seat and be a gynmist to get to it. Most customers turn its circuit into an ignition kill switch and do not replace it.
Next suspension and tires are fickle. At oil change intervals check all ball joint for wear and keep monitoring steering damper for dents and leaks.When this puppy goes you'll have steering wheel oscillations. very easy to replace and not that costly.
Tires just all around **** with this car. If you get 25k out of a pair( regardless of what brand) you did good.
If you have a manual transmission shifter rattles in third gear.
valve cover gaskets every 3-4 years
Calipers leak, there is a TSB on this basically hunt down a good brand and use them.
R4 A/C compressor is very fickle usually dies within 4 years of service.
A/C control head is in a bad spot and is effected by road conditions. pays to have extra parts for this hanging around ( vacuum valve,and setting switch and clear plastic cover)
Also good to keep power window switches handy.
Power seat motor usually good in all positions except tilt position.
Power seat connectors prone to fail due to corroded terminals.
Water pump goes every 50k .
lastly leaf springs , replace silencers every 25k or when squeaking is unbearable.

Either shifter needs adjustment or the gear is worn. I recommend bringing it to a transmission repair shop. The shifter adjustment is a bit of a pain and I would hate to have you go threw all that trouble only to find out its the gear .
Blower motor will not run.
check all ur fuses as a first step, should be under the drivers side of dash, usually the most common fault, if not check for power at the unit itself
My instrument lights not working on my 81 corvette
Check the fuse to see if it is blown,be sure to have the head lights on,and the dash dimmer on all the way bright,when checking the fuse,if it is not blown,check the fuse to see if it has voltage on that fuse,if it does not,then replace the head light switch.If the fuse has voltage to it,then either a bad connection at the cluster,or the bulbs are burned out in the cluster.
