I will post more once completed, I have been searching the world for a new seal for about 5 years now - they are pretty rare as most of you know , I found one - I believe this will also fit CJ5 - there have been many posts on the internet trying to describe what the rubber looks like - so here are a few pics ... its been close to -40F/-40c here at times last couple of weeks so its slow going ...

will post an upright installed pic once done ...

its a nice tight fit, its no easy task as I have a little rust in the channel which makes it a hard pull getting the rubber through - liquid soap and syntectic oils made it a bit easier ...

Looks almost as easy (yeah, right) as instaling the rubber seal on the inner frame of the MB, GPW and 2A windshields, (think I'd rather take a severe beating than ever attempt one of those again).

Just curious, but where did you finally locate the seal?

brazil , in the last year been contacting people - my work office has an office there - using a translator etc and a friend I use to work with also - the one I received was (gulp) sorry to say possibly the last one from his source ... I am awaiting answer if I can get more ...

the rubber appears to be of good qualty and a repro cause there are no cracks, however there are some minor imperfections (occasional bubbled dust specs) but nothing that worries me ...

it was 128inches long which doesnt match my 3B part manual but close to the supercede number for 3B/CJ5 ...

get this - it was about $8 US, however to ship it to me ( Canada ) was another +50$, our postie's let it go through without any additional customs so either they didnt care or we have a true 'free trade' agreement

am searching for more - I think with my contacts I can find more but its slow going - 1 SP5Y ( 1 seal per 5 years ;) ) currently - the translation even through my friend is broken english at best - since supplier will change I would bring in another 1 and examine first ...

if nothing else I hope my post is valueable to those still searching and inspiration to never give up ... with the picture above your miles ahead ... I am a big fan of one of the few options available on the 3B :)

getting closer - havent closed it yet due to some old sillycone build up - but initial fit looks good ... due to channel rust I had to cut the rubber a couple of times to reduce the drag pulling it through ...

its very cold here - warming up in 2 days - will try and close/align it then

edit : original picture had inner frame mounted inside out ... above is correct

George from George's jeep parts in Mississippi had several vent windshield seals for cj5's a while back. He also had two cj3b (M606) NOS vent frames complete with glass.

He sold those to a guy in Indiana, but he may have gotten more since then.

The cj5 seal and the cj3b seals were identical except that the cj5 seal was longer than the 3b seal.

He has a web site, and it will likely say he is in Louisana. He moved a few years ago to Mississippi, but never changed the info on his web site.

I haven't checked recently, so he may have corrected the address.

I have his phone number here somewheres if anyone is interested.

I haven't tried it, but the M35 windshield seal might work. The primary difference I can see is that the M35 had square corners and the 3b/5 had rounded corners -- I think you could trim those squared off corners with a razor knife, and perhaps do some minor modifications, but I think it could be done.

M35 seals are fairly common to come by and are cheap, so it could be worth a try.

the M35 seal wont work, though the windshield has similar hardware and functionally same idea the seal itself has a female groove in it inwhich the windshield is inserted ...

following photo is M35 seal on ebay right now

whereas the 3B seal is a male T design that slides into the metal frame channel ( top most picture in this topic )

I will ask Derek if he wants to save the cross section photo above for future reference , I could also add some micro measurements ... though possibly not exact to original it works ...

yes I believe the seal I installed which is longer than in the 3B parts manual I have will also fit the early cj5

yjcanibul - January 4, 2009 07:29 PM (GMT)
It Fits ... fully open and close with ease ... am very pleased

its possible to mount the seal and/or frame backwards, upclose the flat edge of
the seal rides inside the outter windshield grove as in :

hello everyone, i've used the parts and inner gasket and frame from a 55 civi cj5, it took a little doing but it dose work, my problem on my m606 is that the inner frame was rusted badly, thus allowing my glass to fall out on my hood and into the street, it was'nt as funny to me as it was to the teenage girls on the corner that saw it happen, could someone follow up with me about this george jeep guy's number, i'd like to get some extra parts if i can find them, thanks, m606 cummins turbo diesel, the one the only.

I havent seen the inner frame for sale by itself, I have seen used assemblys inner/outer frames on ebay usually without the seal and glass ...

jyotin would known best , when I google it I find "Georges Jeep Parts in MS 601-542-0013"

in my parts guide the inner frame original part# for 3B were

687715 lower
687716 upper

the ventialting windshield for early cj5 has different part # number for assembly, the parts break down has some parts in common , the inner windshield frame is different though due to it being a split windshield glass unlike the 3B

pic from - note the top hinge and inner windshield differences

there are not alot of close up pictures on the internet of the seal and inner frame, most are from a distance , the seal looks different in almost all pictures - sometimes thick and bulky - sometimes it looks almost like leather ...

anyone interested in bringing in more seals ?

yjcanibul - January 18, 2009 05:51 PM (GMT)
thanks to Larry (Tx) for providing pictures of his 3B with original seal which is in remarkable shape being +40 years old , here are some pictures

thank you Larry
