[Convertible top seals]

I forgot to mention, I need the forward seal on my Avanti quarter windows.  I suspect that Avanti Motor Corp "borrowed" this seal from a regular production car, but I don't know which one (Renault? LeBaron?).  This is a rubber seal held on to the quarter window by a metal flange.  The door window closes against it.  If anyone can give me a lead on finding this seal, I'd be very appreciative.

 

[Convertible top seals]

I changed the seal on my '88 Avanti Convertible about 2015.  I compared the profile of the Avanti seal with ones that I found online for universal automotive weather seals and it worked out fine. 

On the old seal, I found the number 7659, but I don't remember if that was helpful.  Here are pictures:

Here are the seals profiles:

Original seal on left, replacement on right.  The original had a zigzag reinforcement wire running inside it and the new seal was stiffer than the original.

I believe the vendor was Classic Industries (800 854-1280), but I couldn't tell by their website when I looked tonight.    Looking back, I saw an email from them in 2015, but it simply said that their tech would be in touch with me.  Seems like they provided me with a way to look at profiles of the seals they carry.  Other vendors may help you find an appropriate seal.  I don't remember if I asked for a sample piece from the vendor before ordering.  I'm surprised that I didn't find the invoice in my Avanti files, I'm usually pretty "retentive" about such things since all of my cars are "odd" and I tend to keep them a long time.

I have not completed this repair (illness in family), but this topic from the AOAI forum seems like it's the right solution:

The convertible quarter window mechanism pictured above are Driver's Side.  Two nuts on lower photo (above) secure the motor.

Latest issue of Avanti Magazine reminds owners to spray console switches with WD40 and work them well to remove corrosion and improve current to motor.

[Avanti Convertible Side Window Sweeps]

Good news; I think I've found solutions to my quest to replace the window sweeps on my 1988 Avanti Convertible, so I'm passing on these resources to forum members who might need the same.

 

I found this video by "tuscancmh" on YouTube: https://www.youtube.com/watch?v=qQdvpEwl2ro

This video covers changing sweeps on a 1989 Caprice bodied Avanti, but procedure and parts are the same for 87-90.

 

Here's a place to purchase the sweeps -  www.ocautocarpets.com and directly to the item: https://www.ocautocarpets.com/wn-product/beltline-kit-front-door-12pc-19384/1988/?gclid=Cj0KCQjw7pKFBhDUARIsAFUoMDZJWZM0l5KdJ_HhhFjKBJ_W5poQHZNzWgb3jDyX0F0puxZPFkijoyAaAtK_EALw_wcB

 

The sweeps fit the Monte Carlo and Caprice platforms.  I've ordered them, but have not rec'd shipment yet.  If there are any problems, I'll let pass it on.

 

I hope this is helpful should you need it.

[Convertible top pump]

I know that Avanti convertibles are pretty rare, but I was shocked to not find any references to the hydraulic pump for the convertible top.  Maybe I didn't find the magic tag word.

While repairing the quarter window of my 1988 convertible, I found a small (just an ooze) leak of hydraulic fluid at the point where the hydraulic line enters the ram in the quarter window well.  I tightened the brass fitting and didn't see more leaking after putting the top up and down a couple of times.

When putting the top back up, I had been noticing that it tends fall/smack the windshield header as it approaches that area.  Is this normal/expected?  In case it was due to low hydraulic fluid, I searched for the pump, finding it below the cover board in the folded top area behind the back seat.  Picture attached.  I didn't see any obvious reservoir for fluid, but only see the little rubber plug at the end of the cadmium colored end.  Is that for adding fluid?  What kind of hydraulic fluid is specified?

Motor Window World repaired mine recently.  No broken parts, apparently just frayed cable/guides replacement and cleaned motor, $225.  Here are pictures that Jim S asked for in his other post.  Yep, it's a bear to get in and  out - removing the two screws that hold the motor onto the frame (not motor to gear hub) is the key.  Not necessary to remove motor, just slide it out of the way to clear bracket and window slot.
