Best wishes and providence on your effort! Definitely a passion (and time). Not as easy or quick as they present on those car resto/custom shows.

Cleaning up the last rusted section of rust on the front. This area had several rust holes that went through the trunk floor to the torsion bar mount (from a leaking headlight bucket). It was also affected by the shoddy repair of the driver's front corner and the pinch weld at the front was mostly detached/rusty.

If anyone has a picture of this area with the reinforcement plate off, that would be helpful!

Torsion bar mount, will be welded on the bottom. Very little rust on this piece.

Corner reinforcement plate (old one was completely rusted through).

Will do, this area under the trunk corner support would be covered on yours (unless someone had removed it). Not a big deal, was just curious what the metal looked like before it rusted away!

Wire wheels, lots of work and takes forever. Blasting is better if you're able to strip the car down.

Keep going. Such a bummer to have to fix previous repairs that were a bit shady but you'll know it's been fixed right this time! (IMG:style_emoticons/default/beerchug.gif)

Replacement piece welded in. This would have been much easier with a salvaged piece, fabricating the piece took forever and isn't as clean as I would have liked:

Weld through primer:

Fortunately this corner reinforcement will cover most of the repair:

I purchased a large lot of parts with another car which included a rotisserie. I'm hoping this speeds the project, but it has taken me a few days to modify the rotisserie and some door braces. I'm going to tack weld the square steel tubing to the long (where my finger is) so the doors can be put back on the car.

I removed the interior so I could weld my door braces on, and made an interesting discovery. It looks like someone has cut into the inside long and stuffed it full of fiberglass insulation? There are aluminum covers pop-riveted over the large round holes as well as duct tape and some duct tape inside the long on the heating tube.

Trying to decide what to do with this. I can access the inside of the long from these holes and probably knock off most of the rust with a die grinder. I was going to use the 914 LTD reinforcement kit (already purchased), but the inner long reinforcement kit would cover this area nicely. I'm also curious if treating this rust inside the long with Ospho would be sufficient. The outside looks ok, and I'm not sure I'll gain much by opening it up.

The metal covers:

The holes and insulation:

Outside of the long:

Loose rust inside the long, doesn't look too bad:

Is the new car at the house on 40th? I peeked over the fence and did'nt see it. Come over and knock on the door if you're so inclined.

(IMG:style_emoticons/default/WTF.gif) The stuff previous owners did to these cars never ceases to amaze me. (IMG:style_emoticons/default/lol-2.gif)

If there is a competiton for most abused model of cars, 914's surely must be near the top of the list.

I know you probably don't want to hear this but you really should open it up and just do it right once and for all.

I see pin holes on the outer long. That means the inner is side of the outer longitudinal has been rusting from the inside outward. You can put the LTD long kit over that but you'll basically be covering over the lower portion of the rusted long outer. You look like you have the skills to do it right.

With that level of rust and previous owner damage to the inner long you really would do well to just fix it right. That inner long is what the seat belt attaches to. That big hole cut above the seat belt anchor is dangerous and will lead to the anchor just tearing out if it were in an impact.

The C-shape section of the long inner is where much of the structural strength comes from. Once that C section is closed out by the long outer you have a box section that is quite stiff and is the main structural element. You most definately don't want a lack of metal integrity there.

I feel your pain and the desire to do it as quickly as possible and potentially with the LTD, or Engman inner long type kits. I had very similar challenges on my car upon discovering that the longitudinal rust was more extensive than I had hoped when 1st bought the car but my car is certainly worse than where you're starting from.

No, over at my place. I'll stop by next time I'm over there.

Yeah, I took a closer look and I think that has to happen.

Car is on a rotisserie now, planning to cut into the long tomorrow. I'm thinking I'll start by reinforcing the inner long from the inside of the car because I'm worried the car will distort if I cut the outer long with the inner long weakened as much as it is. The other option would be settling it on the jack points and then cutting into it. Anyone have any insight on this?

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23821-1585805809.1.jpg)


I also took a crack at repairing the nasty front trunk seal channel with some steel and a harbor freight bending brake:

I used the rotisserie to lower the car on to the four jack points and then checked with a laser level to ensure everything was level (see laser near bottom of long in the picture). Door gaps were not far off, and adjusted nicely with the door braces.

So the heater tube is gone and the long is stuffed with insulation....The heat must have had an interesting aroma ?

Lol, tube is still there. Just had insulation around it for some reason.
