If you want to up date your dash this will help has been asked
a few times.
Hello there All if you want to keep with in the 73-87 set up . A brake down of the Dashes from 73-87 & Face Bezels changes
1973-78 Chev GMC Dash Pad
1979-80 Chev GMC Dash Pad with V.I.N. cut out;
1981-91 Chev GMC Dash Pad
Now 73-78 Vin on the post should not be used on the 1979 to 91
trim plate will be different . But only a few places will get the 73-78 style, oh & the speaker only in the Center.
The 79-80 will fit the 73-78 but have the Vin hole cut out, oh & the speaker only in the Center.
The dash in the 73-80 are more rounded on passenger side.
The 79-91 are more flatter on passenger side.
And the dash insert 73-80 do not fit the 81-87. The Vin plate is in the corner on the driver side.
Most places have it or can get the 79 and up styles due to the VIN opening
The 81-87 Face Bezels will not fit tight on the 73-80 Dash pad.
The part of the 81-91 pad has a 1" over hang @ the Bezel. So you
have to use the 73-80 face Bezel. The 81-87 Bezel sit about 1/2"
from the edge around bolting area of the Bezel.
The 79-80 Dash pad will fit on the 81-87 steel framing, But you will not be able to
uses the left front speaker. Unless you take out the driver side dash clip.
If you want to make the dash clip work you will have to make a slot for it about
3" to the right you will see in the (1 )
Now for the right side dash near insert cut out for the 73-80 dash on a 81-87 steel framing
you will have to drill one hole to enlarge the steel hole. Where the mounting tabs
go through because there off set a little on the 81-87 for the 73-80 dash
insert plate. Mostly the far right. (2 ), (3 )
Now if the 73-80 Dash is used, The Face Bezel from 81-87 will not
fit tight to the older dash.
The 81- 87 dash has a 1" to 1-1/2 inch over hang over the Cluster area
Compared to the 73-80 Dash pad.
The 73-80 Dash Bezel & amp; the 81-83 Dash Bezel all have the wiper switch on the dash Bezel.
How ever the Cut off point is 73 - 80 not as thick as the 81 - 87 Bezel
The first year was 1984 for the wiper switch to be on the Steering Column. So the
light switch was moved up a little from the 73 - 83 bezel & the the metal dash backer.
You will have to do some modifying to the metal dash backer to move the light switch up a little if you want to use the 84-87 (4 ) Bezel on a 73-83
(6 ) Need the 73-80 dash pad to the work with the face bezel 77-79 style. If you want it to be factory you need the 73-78 dash pad if you have the vin on the post.
(7 ) Face Bezel 75 style see the different from 73-74. has to used With the 73-80 dash,& pad too. .
(8 ) Face Bezel 76 style with wood over lay.
(9) Face Bezel 73-74 style has to be used Will the 73-80 dash,& pad. .
