Talk to me about your stock 50 Pontiac tail lights. NO, Not the re pops. Did Pontiac make more than 1 size in Dia light? I have a nice pair of housings with no lenses. The part numbers on them are 5939885 and 886. They are marked for left and right. A Google search brings up 50 Pontiac tail light. My problem is these housings seem to be to large for any lenses I find. Looking at photos I can find I don't see any sign of thick gasket or seal. These housings are 4 3/4" O.D. and 3 9/16 I.D. Who has one they can photograph apart or get me an inside dia to help out? Did the Chieftain and Streamliner have different size lights? Were all lenses Glass or Plastic? Did they come both ways?
ok the rh housing has an OD of 3 9/16 ID @2 1/2 (where the bulb mounts) total OD of the lens is 3 1/4 bezel OD is 4 5/16 ID is@3 inches the only number on the housing is R-23 or 28 same with the left they each (bezels and housings ) say top rh and top Lh respectivly
OK,,What body style did they come off of? The part number on mine are hard to see. They are inside the gruve on a flat pad and very small.
her car is a fleetline (fastback) body ive got hers laying right here give me a bit and check them again
Looking from the back side and with the lens retainer removed. The groove is what is the crest of the ring on the Chrome exposed side.
All 1949-1950 Pontiac passenger cars had the same tail light EXCEPT - the station wagon and delivery. Those lights were different. Same goes with 1951-1952 Pontiacs. The 51-52 are bigger in diameter than the 49-50.. They are side specific. The mounting studs are different.
OK, My ring is different than the 50 Fleetline so maybe they are 51-52. Do you happen to know the O.D. of the 51-52 housing?
the answer is yes...two sizes. my '51 has larger ones than say a '49. I bought a set of glass blue dots, all excited, only to find they were too small for my factory '51 housing.
This ebay listing shows your bezels, lists them as 51-52 with a note that says "should be 49-50 also". Taillight King shows that casting # associated with 51-52.
^ no, it says "should be" and they are wrong. come to think of it, my '51 has 3 1/2" across lenses...
I can see 3 1/2" across the lens. I was measuering inside the relief from the back side. So if you had the lense in hand it would be a bit larger. Are those lenses Glass or Plastic? Is your housing 4 3/4' ?
The lenses on my car are glass. Most lenses I have seen have been plastic though. I just got a rough measurement of my housings and lens... as I posted I measured about 4 1/2 - 4 3/4 on the tail lamp housings for the 51-52 Pontiac. My lens was roughly 3 1/4 - 3 1/2" in diameter. The lens by itself for the 51-52 Pontiac is about the same size as the entire 49-50 tail light housing OD...
Thanks for all the help Guys. So what I have are 51-52 housings. Now I need to find a pair of Plastic lenses being one of my housings is a bit out of round where the lens seats. I'll need to file it a touch to get it in. Not willing to try to Grind on a glass one. Once again,, Thanks The Wizzard
my OEM '51 is plastic...edge to edge across was 3 1/2" ...a '49 is 3 1/4" that is the answer to this entire thread...they are indeed different.
You are correct, they are different. Also I just bought the 2 lenses shown above your last post from Pontiac so nothing else is needed. Thank God for the H.A.M.B. By the way, they are going on my 30 A Roadster.
both of these sets are originals. Hard to see here but the roadster has old glass lenses with blue dots. The lenses came out of 48 housings with the curved housings for the body location. Some how one got cracked. It does not emit any white light so I left it. Real glass blue dots are pretty rare so maybe somebody will notice that even though one is cracked. It's a gennie. It really pissed me off when Drake started making the repops. That's OK I know.
