Shroud:
7828403 (1978-1981 A body)
Measure the length of yours so you can compare to others you may find.
I think the Monza shroud is way too short. It is almost 40 years since I put a Monza manual transmission tilt column in my Vega.
I have never seen one from a Citation (X body): 7839625
Chevette may also be too short, not sure: 7827922.
Third gen F body up to 1989: 7839625 (same as the Citation)
1982-1985 S10: 7839625 (same as Citation and 3rd gen F body) I don't know how this one differs from the later years.
1986-1990 S10: 7846295
According to GMPartsWiki.com, this shroud also came on:
1979-1984 CK 1, 2, 3 trucks (book published in 1984)
1979-1983 CK 1, 2, 3 trucks (book published in 1987; why does it disagree with the older book?)
1978-1980 Corvette (books published in 1980, 1981, and 1983)
Rack:
7844651; only sold as part of a kit
Make sure the rack you buy has the same number of teeth as your original one.
According to GMPartsGiant.com, "
This part fits specific Buick Century, Lesabre, Regal models. It fits Cadillac Brougham, Deville, Fleetwood. It also fits Chevrolet Blazer, Camaro, P30. This also fits GMC C2500, Suburban, Yukon."
Don't over pay for this kit. Here is are 2 examples of a good price, but I don't know about shipping on the first one (JCA Parts). There are also eBay and Amazon listings that may have shipping already included. I have included an example eBay listing.
If your ignition lock cylinder wont return to the run position after you turn it to start, then your ignition rack gears are most likely stripped out. The gear is plastic and wears over time which in turn, will not be able to actuate the ignition switch when you turn the key to the start...
