Convertible Top Rear Tension Cable Adjustment?

Hi all-

Are you ready for some football?

My car is in storage but one of the things I will try to do in the spring is make the soft top's rear tension cable tighter as it is now quite loose.

I searched and found a couple threads including a biblical length one but I need to address specifically only the rear cable. PO replaced the top at some point and all else is fine.

I hope this is relatively easy.

Please advise. Thanks.

The rear cable goes from the lock down bow to the bow above the window. The cable can be adjusted at the upper bow by peeling back the canvas to reveal the pigtail of the cable and a screw. Loosen the screw and pull the cable. However....if it's an old cable it might break where the screw has been pressed against it.

The lock down bow can also be adjusted fore and aft......aft would tighten the cable.....but it will also throw your lock down pin off center.

Maybe it is off center?

Thanks Nobby. BTW kudos for tackling the top replacement DIY and providing a detailed thread documenting it.

If the old cable breaks I know they are available but what needs to be done to the bottom bow then?

How do you adjust the lock down bow fore and aft and how would I know if it is off center?

Sorry for asking what might be stupid questions.

Thanks.

If it is off center....the lock down pin will not go into the hole on the back deck properly.

Anyways......that adjustment is a little harder once the top is on and completely glued. The adjustment bolts are on the forward ends of the bow.

What am I seeing in the second picture?

So, if I need to replace the cable, I understand what needs to be done to the top bow but what needs to be done with the bottom bow to install the new cable.

Thanks.

Second pic is an inside shot of either the left or right side adjustment bolts for the bottom bow.

The rear cable has a crimped stopper on one end.....it slides into the bottom bow.

I see now. Thanks for the image. One last question as my car is stored in a remote location and I can't look at the bottom bow to make a determination.

Will any of the top fabric on the bottom bow need to be peeled back or does the stopper just slide in?

I don't recall...exactly....but it is in the center and so is the pin. So getting at it shouldn't be too hard. It might be under the rubber seal.
