Thanks Dave......Again, glad to have ya here
I had a couple guys PM on me with a bunch of questions for my outer wheelhouse replacements. I figured it would be a bunch easier to reply by just posting here. Hope this helps guys.
I cut right along the panel before the rise avoiding drilling out spot welds mainly because Mopar did not hold back on joining the outer to inner wheelhouse. I would say there is a weld pretty much almost every 1/8" to 3/16" of an inch. Way too time consuming to drill all out and I would just end up with a mangled lip to rejoin the two.
The front 18" does not have a raised edge so I used tape to use as a guide line for my cut.
There is 3 to 4 spot welds that join the outer wheelhouse to the rocker which will need to be drilled out. Tenderly continue your cut for outer wheelhouse removal. Use a cutting wheel and be careful not to cut through the trailing edge of the rocker
To drill out, hit with a center punch then use a decent spot weld removal bit. The one I use from Blair Tool in Michigan (which Matt so kindly recommended), works excellent! It has a spring loaded pilot and the bit chews through metal like a champ.
When I got those spot welds drill out, I cut around the large torque box and the small rear one to remove the bulk of material. To remove the rest of metal in those areas you'll have to use a cutting wheel from inside the wheelwell. Again, be careful to just cut through the old outer wheelwell material and not through the bottom of the torque box. There is also spot welds on both torque box attachments that will need to be drilled out.
Take your new panel and a good body saw and cut along same ridge. For the front area that does not have the ridge, take the old piece and trace the outline of your cut. I'm always a bit generous on leaving a bit extra metal on a cut like that. It may need to be trimmed but it is a whole lot easier than if you take too much metal off
Once you are completed with the daunting task of fitting up, which usually involves putting in place, trimming, putting in place, trimming, and so on, start making your small tack's to secure. The metal is still thin enough where I wouldn't recommed a continuous welds, but overlapping tack's. Make one tack, move 3-4 inches, do another and so on. Be sure to let the panel/weld area cool before starting over again
After completing your welds, flaten them out a bit with a grinder or small stone bit to eliminate any pits or divets that could hold settling dirt/moisture down the road. I treated the heat affected zone, weld, and known corrosion areas with rust bullet. Be sure to blast, wirewheel or sand any other areas that have light surface rust before applying the rust bullet or what ever product you use. I will also coat the area with 3M rubberized undercoating to level out and protect the area even more. Also, I did not have a pic for drilling new holes in the front of the outer wheelwell where it lines up with the rocker due to the fact I need to replace my whole rocker. Just pre drill 3-4 1/4" to 5/16" holes that will line up with the trailing edge of the rocker and fill. You will obviusly need to weld in the drilled out spot welds in the two torque box areas as well.
Since I had a bit more time today, I also coated the trunk pan to inner wheelhouse seam with rust bullet again since it is all welded up now. Once cured I will use 3M brushable seam sealer in this area to keep dust, dirt, moisture out just like the factory did. I also painted the inside of the rear crossmember, bottom area of trunk pan where it secures on, and the ends of the frame rails/ shackle mounts with rust bullet, since this is definitly an area where these cars love to rot out
I also got a chance to remove the rear windshield. The car has the glued in style mounting with the lovely black tar goo. Against all my better judgement, I went to Harbor Freight to buy this winshield removal tool. I couldn't find on anywhere else...If it breaks, screw it, i'm out 12 bucks. Anyway, it comes with 2 T-Handels a bunch of brass wire, and a slim jim type tool to push the wire from one side of the windshield to the other.
I ended up not using the little slim jim tool, but was able to pry the rear windshield up just enough with a trim removal tool to push half of a 5 foot long hunk of brass wire through
Once the wire is through the inside and outside, slide the wires into your T-Handles and secure. You will obviously need 2 people for this technique. When you start pulling the wire around the window seal, be sure to pull in a manner both people pull the wire along as flat to the window as possible. This will reduce the chance to get snagged up on the cars metal under the glue strip and the trim clips if you haven't removed them yet. Once all the way around, have the person inside gently press out at the top of the window tilting out, while being held by the person outside. Get both parties then to remove the window completly by tilting to about 45-65 degrees then lifting up. Good luck!
Time to end this novel...Hope everyones elses projects are going great, and talk at you folks soon!
