1969 Ignition Shield Install
Can anyone out there give me advice on how to install the left front ignition shield? I took out the alternator and I still can't figure out how to get the shield on. I'm thinking the only way is to disconnect the motor mounts and exhaust to lift the motor up. Maybe the answer is to trim the shield a little? Appreciate any help someone might have.
Thanks,
John

i am trying to understand the issue. in this pic
on my car the shielding behind the ALT on my L-46 is held on by 2 wing nuts.... and the wire going through the hole comes out with a gentle tug.

There are two pieces, a braket that goes on the block and then there is a chrom shield that goes over the bracket and is held on with wing nuts attached to tabs that are connected to the exhaust manifold bolts. I've installed the bracket that bolts to the block, but the steering box appears to be in the way and I cannot position the chrom shield so it can be mounted. Maybe I need to either move the steering box or lift the motor. Seems like I'm doing something wrong if I need to do that.

My engine is installed, and I'm trying to attach the left front chrome shield. The steering box seems to be in the way and I can't seem to be able to position the shield so that I can be attached via the wing nuts to the tabs that are mounted to the exhaust manifold bolts. There is not enough clearance to rotate the shield on.

ALF- I thought of a better way to describe my problem. For the left front shield in your picture (the one by the water temperature sensor) if you unscrewed the two wing nuts would you be able to remove that shield? I don't see how you could and my problem is I'm trying to install mine. John

jyoconnell,
I DO NOT have power steering, so i assume you are talking about the steering gearbox being in the way and not power steering pump..?
It's been below 32* here so i have chickened out goin' in the garage and testing taking the plate off. If you need me to I will...?

I did this with a tune up last spring..that one is a bugger to get back on..I remember loosening the manifold bolts that held the brackets for the shield..rotated out of the way and wiggled the cover back in place..I always wondered how it came off and wouldn't go back on..oh well hope this helps..

On some cars this shield can be tough. If I remember right I remove the front wing nut,loosen the rear one,loosen the rear ex manifold bolt and then remove the shield,rear bracket,spacer and bolt all at the same time. If the car has the brake line block it can make you cuss.

How to get the left front ignition shield on

1) remove altenator
2) remove left motor mount bolt.
3) With wood block under oil pan jack up engine 1/2 inch on left side
4) snake temperature sensor wire through hole on shield and connect to temperature sensor terminal. This is necessary because it is almost impossible to get on once the shield is installed.
5) with exhaust manifold brackets (wing nuts) removed slide shield in from altenator side. Wiggle it until you get it positioned close, and past the steering box restriction
6) attach rear exhaust manifold bracket, leave loose until second bracket is in place.
7) Attach front exhaust manifold bracket, tight both wing nuts and exhaust manifold bolts.
8) celebrate!!

Corvette Engineering???
I can not believe that they paid someone to design this impossible to remove and install shield. Since this process has to be done to check and/or change plugs, it is no wonder that almost all 69 corvette have this contraptions removed. I have not had any on mine since 1987 and the radio sounds fine!!
