512TR-Bonnet(trunk) release cable replacement

The bonnet cable on my 512TR failed at the fitting that connects it to the release latch handle. I ordered a new one from Ricambi. The emergency release works fine, so "bonnet" is still usable.
Is there a recommended procedure for replacing the cable? I note that the cable is sheathed and the fitting on the end, or the sheathing will not fit through the small hole in the latch handle housing.
Will it be preferable to remove the firewall carpeting to access the path of the cable?

Thanks for any advice/recommendations.

 

Steve,
Thanks for the quick reply. The existing sheath seems to be fine, so worth a shot at that approach before a more radical process. That solves the problem of getting the cable fitting through the handle base. I did notice that the nut on the handle wasn't tightened all the way when I removed the stump of the swaged fitting at handle, so maybe it wasn't too tight, but 34 years of fatigue took it's toll, I guess.

The old inner cable isn't visible at the handle end (has metal end "cap") as it has disappeared into the sheath, but I guess I may be able to push it out once it's disconnected at the latch itself, which looks like a fun process due to the cramped quarters.

Just wondering how easy it will be to feed the inner wire through the sheath.

When I get the part from Ricambi, I'll scope out the options.

 

Steve, are you saying to chamfer the hole on the upper side of the housing (attached photo noting underside of hole) to allow for more movement of the inner cable?

Steve, did you mean on the sides of the aluminum "cap" fitting at the end of the outer cable sheath?

 

Steve, thanks for that clarification and your help. Yes, my car had the updated fitting. Here is a photo of the piece that broke off. I'll post an update after I receive the new cable and try to replace the old one, inner cable first.

Good advice. The immediate challenge will be fishing the inner (or outer) cable from the handle to the latch mechanism under the bonnet. Not exactly a straight shot.

 

Brian,
Ok, thanks for that info.
Currently the old inner cable isn't extended beyond the end cap. So my tentative plan is:
1. Disconnect inner wire/cable at the latch in the bonnet.
2. Push on it, to extend it out of the other end at the end cap. Probably lubricating it during this process.
3. Pull the old inner cable out of the outer sheath at the latch handle end.
4. Attach the new cable to the handle.
5. Push the new cable through and attach it to the under hood latch.
6. Adjust the mechanism.

Any thoughts on that plan?

 

Steve and Brian,
Thanks. I completed the job as planned yesterday. Very challenging to access the bolt where the inner wire cable attaches to the arm of the latch due to the restricted area. As recommended, I had a friend assist with moving the wire cable, while I aligned it with the hole in that bolt. It also took a few repeat tries at tightening the wire cable to insure reliable operation of the latch, but all is good now.

 

Steve,
See results above. Thanks for your help.
