nice look, modern material
nice look Alvin, very period fitting.
use something man-made for the headliner, they are less susceptible to soaking up moisture. Any sort of headlining matl will soak up sound, I wouldn't go with just paint unless the rollbar fit is real tight.
If possible, glue the ends of the weatherstripping together when installed. (Sanford rubber cement at Staples)
this are is prone to getting "very hard to get to" moisture/mold right at the joint, even from just humidity cycling in storage.
Good idea with the eye-bolt. the two I have seen were done that way. Eric H's hi-screen hardtop had bolts bent into a J, so they were like a hook. Marine stores have nice stainless turnbuckles as well.
Let me know if the 3M tape isn't up to constant chafe. We have 1" and 2" teflon tape at work that is $17 bucks a roll, but I think I know where a roll or two could be "appropriated for long term field research". It doesn't do anything to paint, even if left on for extended periods.

I concur. Masking upholstery to avoid overspray, dust and other stuff from the outside finish is going to be harder than to pad a pair of sawhorses and protect the exterior.datsunrides wrote:If you are planning to use upholstry on the inside, do that last.

Additionally, on the hard top to body gasket, you might want to look into using two of the soft seals bonded together before you bond to the lower edge of the hard top. The tops I've got both had an extended and thick cushioned gasket. One of them will actually have to be fabricated from 3 different profiles to come close to the original (which was also made with 3 different profiles). Unfortunately, finding the original profiles is what makes it difficult.
I found that RV repair shops have access to a HUGE variety of different soft closed cell weatherstripping in rolls. Talk to the parts guy and he might allow you into the backroom so you can select the best profile(s) to do the job you want.
Window seal weatherstripping is still readily available and JCW is an excellent source.
Don't forget to buy a Soft Top Weatherstrip Seal for the front bow for use with the front edge of your hard top.

Take a look at this link:

Items 2 and 3 have various different profiles that you can combine to form a wider footprint weatherstrip.

Ordered all of the weatherstripping from JC Whitney, except for the header.
In preparation for paint I removed the chrome trim, and like Wade mentioned it is a friction grab setup. It was stuck on pretty good but I just used a flat blade to pry it off.
I measured the piece to be ~9ft so the new trim for JC whitney should leave me with more than enough!
I'll post pics tonight
Thanks again Wade!

Marine supply stores have this cool non-woven cloth-like stuff, http://www.westmarine.com/webapp/wcs/st ... assNum=623
It is very moisture resistant.

Thanks for the tip Dave, I'm not there yet but I'm debating cloth/alcantara/vinyl for the headliner.
Just like Wade mentioned, here are pics of the chrome trim coming off:



I decided that I'm not going to play with prep/paint so I dropped the top off at Williams to work his magic...it will be PPG black.

hey guys I am ready to re-install the weatherstripping/windows.
What adhesive should I use?
While I have the glass out, anything I can use on it to make crystal clear?

I assume your hard top windows are some sort of plexi-glass. Do a google search for Lexan polish. I use a 3M product and it works wonders!

Michael,
Actually it's real glass(yikes!), I did a quick Windex wipe down when I first got the top but I'm sure I can do a better job.
Also, I am following Wade's suggestion of Dynamat/headliner.
I've never used this stuff, is there a special adhesive for it?
For the headliner I'll use 3M spray-on adhesive.
Headliner color: I was set on a light-grayish color now I'm thinking black. I have a red interior/black carpets, silver rol-bar. Any thoughts?
Here are my choices(thanks to wade for link):

Alvin,
You can get headliner material from the local fabric store. Find the biggest one you can locally and they will have cloth headliner material, vinyl, leather whatever you were thinking of using. They will not have as many colors as the online place but the advantage is you will be able to see samples in person, even buy 1/4 yard as a swatch for comparison to your car.
Lots of women in there and I am sure they will be glad to help you

3M makes an excellent weatherstripping adhesive. Comes in black or yellow. Most parts stores have it.Alvin wrote:hey guys I am ready to re-install the weatherstripping/windows.

Check out Eastwood. They make a glass polishing kit that works very well on lightly scratched glass. another option would be to go and have a new piece cut. Flat glass (if that's what you have) is not too expensive.
