Thanks for all the info, Adrian.
I do not want to disassemble the unit that I have as it is on loan to me for dimensions and pattern. If I can help in any way, don’t hesitate to let me know. 
BTW, the glass is not standard thickness (about .125 th) and tempered on the later models. Check before using a standard window channel, it may be too wide to hold the glass.

Larry,

Old spring is 8.5” long. Nearest replacement I could find on eBay  was 200mm long ( just under 8”). As I mentioned early my replacement spring is slightly weaker but plan to use a 3” long bolt to compress instead of the orginal 2” one. Will also make the tube shorter or the inserts longer at the end of the springs to compensate for the spring being just over 1/2” shorter than the orginal.

No need for a cam but thanks for the offer. I just plan to trace it out onto a bit of steel and then spend a bit of time with a grinder and sanding disks. As for the window channels I’ve bought a couple but none are as long as the originals but can’t see that being an issue. 

So long as the new lift channel is central so there is an equal amount of glass at the end of it I don’t think I will have a problem.

The two different lift channels I bought were on eBay. https://www.ebay.co.uk/itm/VW-Beetle-Type-1-Window-Lift-Channel-873Vg0430-Front/301882320441?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 

and

The second one is longer both have brackets that are no use but not an issue as I’m planning to cut off the brackets below the window channel anyway. As they are from a VW beetle you should be able to find them in the USA.






Not sure how much you have disassembled the window lifter but there is a number of inserts and a bearing in the cam that needs to be manufactured. I own a small lathe so my plan for tomorrow was to make replacements for these.

One thing I have just noticed is the springs I bought are not quite as strong. There is not much difference so just plan to get a slightly longer bolt compress the replacement spring more to compensate.

Thanks, Adrian,
We are thinking along the same track. I will order the spring and I have some 4130 aircraft, thin wall tubing. I am going to have the cam cut at my friends waterjet company. Would you like me to send you one? 
As soon as I get the new belt for my plotter, I can send you the full size layout. Can you open ACAD drawings?
Where did you get the window glass channel?

Hi,
 
I’m in a similar position to Greg as I’m missing one of my window lifters and the other is in extremely poor condition (pressed metal part is badly corroded).
 
Plan to try and fabricate a replacement set soon as some replacement springs I ordered on eBay 4 weeks ago from China finally arrived in the post today.
 
 

 
Will install the 16mm OD springs into the piece of tube, attach the window channnel to the tube with some metal brackets and then will just have the challenge of fabricating the arm that the spring acts against.

Springs came from eBay and are 16mm OD and 200mm long https://www.ebay.co.uk/itm/16mm-OD-Green-Heavy-Duty-Compression-Stamping-Mould-Die-Spring-8mm-ID-All-Sizes/283430128264?ssPageName=STRK%3AMEBIDX%3AIT&var=584449173757&_trksid=p2057872.m2749.l2649

Greg,
I do not have any estimate on the cost. I hve to design  the best way to build it as the original is made of press formed steel. Have considered molding it from KEVLAR  or cutting, machining and welling the components.
I am trying to recourse the spring at the present.
Will keep you informed.

Larry, that would be fantastic.  Any idea about the cost to do so?  Thanks. Greg

Evening, Greg,
I have the use of a window lift to use as a pattern.  It has been loaned to me by Dave Mensh. Do you still need a pair of lifts? If so, I will start blueprinting so I can fabricate the unit.

Rob, that would be most helpful.  Mine is a '68 (registered as a '69) 1600 GT woodie as well.  Greg

Ah, Larry I wish I knew the answer. Frankly, I'm so frustrated that the otherwise fantastic car has begun to loose its attraction for me. It's been about 5 years in progress, and there is light at the end of the tunnel, but I'm almost ready to throw in the towel. It's a late '68 and totally stock. The restorer lost the glass on the right side, and the window lift mechanisms for both sides. Guessing the window shape won't change, but I don't know which shape to tell you. I do have the original frames.. But have yet to figure out how they mount. I'll try the early corvette lift mechanisms. Again, thanks for your help. Greg
