I thought you were going to use headers? If so, good luck with those braces.The braces gave me a baby fit, I finally realized they go to 2 different spots on the tranny!

Do you think you'll be able to reach up there and peal off tape after it's gooped down?Now windshield is going in Monday, this looks awful close to where a ton of black goop is going, should I tape off the front of my nice new pad?
Will masking tape hurt or mark the pad?
Yep. The black goo is what the butyl rope eventually becomes with time.Most windshields are installed using a butyl rope,...no mess.
A-bodies and B-bodies through 1970 use a gasket. I believe pre-fuselage (1968 & older) C-bodies do as well, while 1969-'70 C-bodies use a specific butyl (probably a thickness difference). After those, everything used butyl rope, which is so easy I've done a couple by myself. The least fun is handling the glass by oneself, since you really don't get another shot at it and old glass breaks easily. Still, I've never had a leak. With two people, it's a virtual cakewalk.That is a glass in gasket deal, right? I just hope you have a different outcome than I did when I tried to hire a glass installer to install a windshield. The guy showed up with no gasket and no idea he even needed one. I sent him away.
It sounds like that guy tried to use quick-set urethane, which came along after butyl and really isn't backward compatible. It works in a pinch, obviously. The butyl automatically sets the height of the windshield in relation to the frame on which it fits, and comes with setting blocks to position it correctly between the roof and cowl. The factory installation used six setting blocks and a rubber "spacer" ribbon; the latter rapidly degraded. The extra four setting blocks and the rubber spacer were deemed extraneous and haven't been serviced (or even used) in 40 years.BBB, I don't think mine gets a gasket, on the 73 the guy tried rolling out some foam looking thing, the glass was set too high & I couldn't get the trim on, he came back & just used the goop?
I just measured my OE glass v. the replacement, and the difference is about 1/16". The new glass measures approximately .180" thick where I measured (upper left corner). If yours is the same I'd recommend the thicker rope. That shouldn't piss him off--if he knows what he's doing he should have both widths in the truck with him. If he's going to use urethane instead of butyl, make sure he's got 3/8" setting blocks to space the windshield.OK, original glass is gone!
I'll go out after dinner with the straight edge, it looks darn close?
It will be new glass will I piss the guy off if I ask for 3/8 rope?
The factory part number was 2899351 (two required), but it's long gone and never superseded. The bushings were used on everything except A-bodies after 1970 and stayed the same through the end of the "first RWD" era, last being used on the 1989 M-bodies (Fifth Ave, Gran Fury, Diplomat). I was surprised to see they were ever serviced, since I've never had an accelerator pedal I felt needed attention. Anyhow, they're gone now. You could try taking measurements with a caliper and slogging through the bushing selection on McMaster-Carr's website.I guess the first question should be does anyone have a source for these?
I should've mentioned that, allowing for compression of the butyl and depending on its thickness, the glass will be about 1/4"-5/16" further out than the level of the windshield frame. Like I said, they're very close but they should not touch. Find a couple of hex nuts of the right thickness that you can tape to the windshield frame, then lay your straightedge across those.Holy crap, just spent over an hour trying to get that pad down, crowbar in the corners to get the side adjustments to bottom out & center punches to try & get the 4 by the window as low as they will go, lost the metal that held the U nut in by the vin tag, it's just spinning, will try & crawl under in the am & see if I can reach it?
It's friggen close everywhere & it has a bow up right in the middle of the front, that might still hit, I'm hoping the 3/8 inch goop is wide enough to clear?
They do. I should've written that a bit more clearly. All A-bodies, as well as B-bodies through model-year 1970, use a gasket. '71-up B-bodies use butyl. The 1967 A-body gasket is a one-year unicorn, as are the mouldings and lock strip.Pretty sure all the A bodies use a windshield gasket. I have a NOS one in my pile o’parts.
I was thinking the same thing, at least for my 71. I don't remember it being any different and the trim is off so I would've noticed it.Pretty sure all the A bodies use a windshield gasket. I have a NOS one in my pile o’parts.
