ONLINE INTERCHANGE MANUAL - GLASS SECTION
Most of the body components have been abstracted from sources
like the Hollander Interchange Manual, Chevrolet Parts Interchange Manual,
and the Chevelle Archives. Some corrections have been made, because of
my field experience, like the door handles.
*This piece is commonly interchangeable with all 1968 2-door
hardtops/convertibles, and the vent wing assembly is a direct interchange.
Note: 1968 was the only year that the vent assembly was
present on a hardtop, before GM used the Astro Ventilation system on 1969
A-body hardtops. 1969-72 door glass, for the hardtop/convertible, is a
*The vent glass is a one-year item for 1968s, and this also
holds true for the door glass. The window regulator (which has a crossarm
assembly) and its parts are interchangeable with the following:
1968-72 El Caminos
1968 2-door hardtops/convertibles
1968-72 pillared coupes built by the BOP marques.
There are two regulators used, one for manual windows, and
one for a regulator with a power motor setup. Warning: If you end up with
a four-door vent glass from a pillarless sedan (e.g the wrecking yard),
or if someone has one for sale at a swap meet, don't buy it unless you
want to use the parts from a 4-door hardtop sedan to repair an existing
1968-72 EL CAMINO VENT GLASS
*Another interchangeable piece, in which these are the following
1968-72 A-body pillared coupes (like the Buick Skylark) would
have the same glass assembly (includes the GMC Sprint)
Note: The vent assembly and its components will interchange.
4-door sedan and station wagon will not fit.
1970-72 HARDTOP DOOR GLASS
*All A-body hardtops built by General Motors during this
time period will interchange, and the 1970-72 Chevrolet Monte Carlo door
glass will fit any 1970-72 A-body hardtop or convertible. The window regulator
will also interchange (the regulator has only one arm).
The quarter glass for 1968/69 Chevelle 2-door hardtops will
interchange, and there is a rumor that the quarter glass from an Oldsmobile
Cutlass 2-door hardtop will interchange with 1968/69 Chevelle hardtops.
I have little knowledge for the Buick Skylark; it might interchange with
the Chevelle, but the Chevelle glass (which is smaller) would not fit the
Buick. Another note: the hardtop glass, which includes the 1968/69 Chevelle,
will interchange with the 1968/69 Pontiac Beaumont (Pontiac of Canada),
a Canadian built variant of the Chevelle with a Pontiac-like grille.
1970-72 Chevelle and Buick Skylark 2-door hardtops interchange.
1968-72 Pontiac Lemans/Tempest 2-door hardtop quarter glass will bolt into
a 1970-72 Chevelle hardtop, but part numbers differ.
The hardest interchange of the windshield is complex, which
included different models and bodystyles. This is a breakdown of the body
styles that a windshield will interchange:
1964/65 A-body hardtops are interchangeable with the following:
1964-67 El Camino
all A-body Station Wagons, sedans, and 2-door pillared coupes
exc. 1966/67 Lemans pillared coupe
1966/67 2-door hardtops (including the 1966/67 Pontiac Lemans and Buick
Special post coupe) used the same windshield assembly
The 1968-72 hardtops and convertibles used the same windshield assembly
with one other note:
1970-72 windshields incorporate an integrated antenna in
The windshield from the El Camino and 2-door pillared coupe
will fall into the same category with the hardtop and convertible.
*One warning: a 4-door A-body windshield, which is also a
station wagon part, will not interchange with the hardtop, which is 1"
1966/67 Chevelle 2-door hardtops shared the same back glass
(tunneled like the 1968-70 Dodge Charger hardtop) with the following:
1966/67 Oldsmobile Cutlass 2-door hardtop
1966/67 Buick Special/Pontiac Tempest or LeMans 2-door pillared
1966/67 Buick Skylark hardtop
Note: 1966/67 Pontiac Tempest/LeMans/GTO 2-door hardtop
back glass is completely different, and has no relation to the tunneled
rear window found on 1966/67 Chevelle 2-door hardtops.
The 1968-72 Chevelle rear glass for hardtops and pillared
coupes will interchange with the following vehicles:
1970-72 Monte Carlo
1969-70 Pontiac Grand Prix
The BOP A-bodies rear windows are unique to the bodystyle
used, and this includes the following vehicles that interchange:
1968-72 Lemans/GTO hardtops and pillared coupes used the
same glass for all models,
1968-72 Buick Skylarks had the same rear backlite for all
1968-72 Oldsmobile Cutlass hardtops shared the same rear
1968-72 4-door Chevelle, Tempest/LeMans, and F85/Cutlass
shared the same rear window assembly
1971/72 Grand Prix and 1970-72 Cutlass Supreme "Holiday Coupe"
shared the same component
The reveal moldings, matched to the body contours, will interchange
if taking the glass (windshield, rear window) and the related hardware
from a thrashed out A-car.
There is limited interchange for outside mirrors, in which
options and mirror styles varied. Each GM division had its own mirror style,
with some exceptions. The Chevrolet mirrors are interchangeable, and there
are other models in the Chevrolet marque that would interchange:
1968 door mirrors (the round type) are interchangeable with the following:
1968 Chevrolet full size exc. Impala hardtop and Custom
1971/72 Pontiac Ventura II
Note: this mirror does not have the bow tie embossed into
1969-72 outside nonremote mirrors are interchangeable with the following:
1973-79 Novas (and BOP variants)
