Injector leaking? Could it just be the nut on top is not tight? Or more likely the hoses that are on the sides are cracked and need to be trimmed off and reinstalled.The gauge might just be unplugged or plugged into the wrong sensor on the side of the block on the drivers side. Should be two there one for temp and one for the glow plug sensor. Try switching them around. The windows are going to be a long term fix. I would reglue them now, just seal them up until you can source out the bolt in ones. Start looking for the older models. 82-84 I think. I had to buy two complete doors off a Cabriolet to get the windows, the seals and the metal frame that you have to replace to make the swap. I tried every kind of glue I could find to get the windows to stick to the flat hinges and never did get them to work. Just to many curves and pressures working against you.On the speedo you can disassemble and order the little plastic gears that go in there. The driver of the mechanism seemed to be the weak link so after awhile it wouldn't turn the tenths over any more. Good luck
I used the glue for the glue-on rear view mirrors available at your FLAPS. It's been working fine for 6 months and counting.
Any idea how I should go about fixing the gauge, and more importantly where can i find the bolt in style vent windows? Broken odometer doesn't bother me too much.
