Exhaust heat shield question

('83 12A) I've pulled all the heat shields off the exhaust and above it, and dropped the exhaust pipe and drive shaft so I can drop the transmission to install a new clutch, pressure plate and throw out bearing. Also replacing clutch master and slave cylinders while I'm at it. How much of the heat shield stuff do I really need to put back?

Also, the Haynes manual says there are two bolts in the top of the transmission, but I can only find the one near the clutch slave cylinder. Where is the other one?

Thanks

It's also near the clutch slave cylinder. The clutch slave cylinder is held to the top of the transmission with two bolts.

I recently removed mine knowing that the chances of me parking in a dry hay field after driving a hundred miles are very slim.

the heat shield under teh center console protects from cabin heat. your choice. definatly keep the heat shield by the tank. i cant see why you would remove it just to drop the trans. in fact, why did you remove the heat shields on the underbody??? i can see the ones on the exhaust but why all of them on the body?

I took the ones off the exhaust pipe so I could remove the section between the the manifold pipe and muffler. It includes the pre-cat, cat, and a short section of pipe. Then, I removed the big, two-part, heat shield above the exhaust pipe so I could take the drive shaft off. This gave me enough room to unbolt the transmission and pull it back to lower it with a jack. I've just got the car up on ramps and jack stands, so I needed as much off the underneath of the car and out of the way as I could get it.

Oh, my earlier post about bolts in the top of the transmission-- I had all the bolts out, just didn't have the transmission lowered enough to let me wiggle it to get it off. I got it off this evening, got the inside of the bell housing cleaned up and put the new clutch, pressure plate and throw out bearing in. It got dark before I got the tranny bolted back up, though. There's always tomorrow!

All the heat shielding weighs very little. Removing the shielding from the tank presents 2 dangers. Fist it is a heat shield. Second, it is also a rock shield. if you see little rust spots on the tank, those are from rocks that the tires have thrown up an penetrated both the undercoating and galvanic coating.

Removing the tank shield allows the tank to rust out quicker, your choice, good tanks are getting harder to find.

once you remove it to get to the e-brake cables it's kind of pointless to put it back on.
