Soft Top setup issue after canvas replacing

[thejack]

Hi all,

I hope some of you can address me to the final solution about this issue that is driving me crazy...

Ok, here is the story: I bought a new canvas from ebay (US seller). It is really fine and well manufactured with a soft vinyl rear window. I have fitted it onto the frame with some difficulties due to the fact that it seems to be a bit narrower than the original. But anyway it fitted pretty well. The only problem i had to face with is the frame setting which doesn't seem to sit in the correct position when the top in closed. From the external view, the two side acrches doesn't stay aligned and the front semi arch sits a couple of mm higher than the rear one. Another issue is coming from the locking operation which requires too force to take the front bow as down enough to engage the latch. I have tried different solutions as losing the canvas, registering the drive arms etc. I also have got the workshop manual but no tips at all.
Anyone have experienced the same issue? I will later post some pics.
Thanks in advance.
