If you swap your 129 for a 107, you'll have your wishes ! They are all manual with a few exceptions for a very expensive conversion

Converting to manual operation? Problems with early model years...

I would strongly advise against conversion to manual operation, unless you absolutely cannot afford having the cylinders rebuilt. Manual operation eventually wears out the locks (and it is easy to damage the trim pieces around the locks when you use the soft top tool a lot), plus you risk damaging your canvas around the tonneau cover hinges. Keep in mind how much value you are adding to the car by fixing the top cylinders now, as opposed to going down the road where you have to find replacement locks later on.

On early model years, you may have to take up to eight cylinders out in order to facilitate manual operation. The reason is, the piston seals can swell up very tight and eventually make it next to impossible to move the locking cylinders and the tonneau cover lift cylinders manually.

Please see the following instructions on our website's FAQ page on how to lock your top without cylinders in place:

Hope this helps,
