It came with 11 months rego, logs books & is 100% original down to the hubcaps, factory black trim, carpet & factory fitted Air Chief radio. The body is OK but has minor rust in some of the common spots, so while i've been using the car as a daily driver of sorts, i've been slowly repairing the worst areas to keep it from deteriorating further. The first area that needed attention was the windscreen plenum as everytime it rained the floor would fill with water.
So one afternoon when i was bored, i made a repair panel.
A few hours after work of measuring & trial fitting then i was ready to start cutting away the rusty metal.
A sunday afternoon's work had the section welded in place, sealed & painted. Before refitting the dash etc, i sprayed around half a can of cavity wax inside to prevent the rust coming back any time soon.
Within days, it poured rain but this time the floor stayed dry . Not so the boot. The RH tail light recess was badly rusted allowing water to enter the boot.
The boot floor is pretty good on this car but i knew it wouldn't stay this way for long if i didn't attend to the rusted tail light recess, so i started by making a repair section one afternoon when i had nothing to do.
The fun part of cutting the rusted area out. This was one of the most challenging rust repairs i've done to date.
I spent the best part of a rainy saturday doing this repair but it turned out OK so i'm happy.
While i had the welder out, i attended to some minor rust on the sills. The car has a stainless steel trim mould affixed to the top of both sills & rust had come up around the welded studs & plastic clips that attach the mould to the sill on both sides.
This was also a tricky repair as i am retaining the stainless moulds, so i had to weld & grind without damaging the studs. I cleaned the rust up as best i could with a small air sander & a die grinder with a wire wheel, then used a silicon bronze welder to fill the holes. The silicon bronze welder doesn't generate as much heat as a MIG, therefore it doesn't blow holes as easily, doesn't distort the panel as much & the welds are alot easier to grind. The finished repair, all studs intact & very little body filler needed.
I've done these repairs, plus a couple of other minor ones, over the past three months or so when i'm not restoring my SL/R or working on other people's cars. Next repair is a cut-n-shut on the lower radiator support panel. It is completely rusted through the tie bar & the rust extends along the base to where the front guards bolt on, so it's easier for me to replace the whole length of the lower support. I managed to score a damaged support that is actually rust free here so it'll be a good challenge to do the cut-n-shut while the original support is still attached to the car.

Excellent work there!
Did you happen to keep a template of the repair section you made?, I am sure there would be alot of people out there that could use that part under the dash.
Look forward to seeing photo's as you progress with this car.

Someone in the car's past had bogged the rust in the apron, it was so badly rusted two of the bolts came away with the apron when i removed it from the car.
Even though repair sections are available, i am using a damaged second hand support panel to do a "sectional repair". This way once the repair is finished, it will retain the factory original appearence & the repair will be hard to pick.
I began by unpicking & cutting away the rusted tie-bar.
Then, i started cutting the tie-bar from the donor support making sure i left plenty of "overlap".
Then i sat the replacement tie-bar on the car & held it in place with vice clamps. During this process i also trial fitted the guards & replacement front apron panel to check alignment.
Using an air hacksaw & cut-off wheel started trimming the replacement section to "butt up" to the radiator support. As i'm joining it behind the factory spot welded flange to "hide" the repair, i had to remove the tie-bar & unpick the excess steel. This is where i became so involved in the job i neglected to take pics but here is the section welded in.
I welded from behind where i can lightly grind the welds & hide them with stoneguard, on the front face of the support where the penetrated welds were visible, i used an small air sander & belt sander to sand them flush.
I haven't welded the flanges beneath the front bumper mounting recesses yet as i will use the inverter spot welder at work to spot weld them to replicate the factory appearence. For the time being i applied some black etch primer & GMH black to seal the repair from rust. I'm pretty happy with how the repair turned out, no bog will be needed to hid the joins as the gloss black finish shows.
I also used this oppertunity to replace both original guards as they were badly rusted & had several substandard repairs.
The front end all back together. It actually has better panel alignment now than what it had before i started the repair.
Next step in the repair will be to spot weld both flanges & give the whole support a coat of GMH black.

It is still registered & goes alright, has enough stick to do this to a 28 spline Borg Warner axle.
Thinking of putting the running gear into my LH but not 100% certain yet. I kind of like the 173 & column shift tri-matic, but they are showing their age & the Torana would be alot of fun to drive with a nice V8 in it. Got a couple of months to think about it.
