Interchangeable Parts for GMC Trucks with other makes
 

Someone suggested having a thread about interchangeable parts in every category and it sounded like a good idea so heres one for dashes and interiors.

I just went through a bunch of places looking for dash bulb sockets. I found this part at Rock Auto.com AIRTEX Part # 6S1037
You want the 5/8 inch one, not the 1/2 inch one.


For dash bulb sockets the GMCs used the same bulb sockets as
1958 Cadillac Series 62 with 6.0L V8
1960-65 Chevrolet Impala with 4.1L L6
1963 Buick Special with 3.2L V6
1967 Oldsmobile Cutlass with 6.6L V8
1969 Chevrolet Corvette with 7.0L V8
1969 Chevrolet Nova with 3.8L L6
1969 Pontiac Firebird with 4.1L L6
1971 Buick Centurion with 7.5L V8
1974 Chevrolet C10 with 7.4L V8
1974 Chevrolet El Camino with 5.7L V8
1977 Chevrolet K20 Suburban with 6.6L V8
1977 Pontiac Grand Prix with 6.6L V8
1983 Chevrolet K5 Blazer with 5.0L V8
1984 Oldsmobile Delta 88
1984 Chevrolet S10 with 1.9L L4
1987 Chevrolet P30 with 4.8L 292 L6

Some of the OEM part numbers that are interchangable are 249679, 2973932, 3509575, 356, 5655006.

Hopefully thats enough info for us to find them somewhere else if rockauto stops selling that part.

Hi if you are replacing your turn signal switch and can't find one to fit a 63-66 GMC a 63 chevy one will fit it has the same bolt pattern. Here is a link http://www.bobschevytrucks.com/1963-...hout-tilt.html give that a look...Vernski:D

Here is the same one cheaper

Another problem that is like the turn signal switch is the dash knobs, I ordered some from Brothers trucks and what did you know they sent me the wrong ones instead of a 65 GMC knob they sent one for a 65 Chevy. The GMC is the large knob, the Chevy is the small knob. It appears that the 63 Chevy is the large knob and the 4-5-6 Chevy is the small knob. Every parts place thinks that Chevy parts is the same as GMC in this case 60-63 chevy is but not a 4-5-6-chevy. Little things I grant you, but important if you order from a ignorant parts house...Vernski;)

Thought I would let other members about a parts house in Dayton Ohio.
They deal in Chevy parts, but I bought a lot of parts for my GMC that will interchange. The web site is www.chevroletrestorationworld.com I found their prices to be a bit better than some of their competition. They have tons of chevy car parts. Don Maurath Cincinnati Ohio 1966 GMC

Vernski: Same bolt pattern is one thing but fitting properly is a whole different enchilada. The Chevy turn signal switch requires a LOT of Dremel tool work. Even then it is not the best option. Much easier (in the opinion of this '64 GMC owner) to use an earlier Chev truck column if your '64-66 GMC turn signal switch is not usable.

I had a hard time finding one that will work, a 63 chevy cup has the same bolt pattern as the 65 GMC the problem is that the parts places keep sending a signal switch for a 65 chevy, well that won't fit the GMC cup. I just changed the cup off of a 65 chevy and then the switch the parts geek sent fit without any problems on my column, set it on turned it a quarter turn to line up the screw hole to mount it solid and make sure the signal stem was in the correct spot.
That worked on my 65 but it may be different for a 64 I just don't know and that's my story. GMC did some wacky stuff in parts fitment over the years so good luck I used the 65 GMC column it came with, BTW the 63 chevy won't work because the color coed is off also, sorry if I mislead anyone..Vernski:goodluck:

Here is another question about parts that may interchange. I have a radio delete plate from a 1964 Chevy pickup. Does the same one fit GMC also?
I tried to post a pic but got an error message.

I think they are the same but don't quote me..Vernski:lolflag:

Thanks for the reply Vernski! I tried to load a pic again today, but still got the "Database Error" message. I know my pics are much smaller than the 8 MB limit.

Anyway, I know that Chevy and GMC had different radio delete plates in the late 1950's, and thought they may still be different for this era.
