Getting ready to hang new sheetmetal...
« on: October 27, 2010 - 04:27:12 PM »
Hey guys,
I’m going to be hanging sheet metal on the rear half of my Cuda soon.  It’s a 72 that I’m cloning into a 70 –  will be using 70 quarters and tail panel.  Below is a list of items that I’ll be putting back on.  Is there anything I’m missing?  I don’t want to be in the middle of putting this stuff on only to find out that I missed something that I need and have to wait a week to have it sent out.  Parts I’m going to be putting on are:

Driver’s side outer wheelhouse (driver’s inner & passenger’s inner/outer are good)
Trunk pan
Trunk extensions (drop-offs)
Trunk braces
Trunk drip rails/gutters
Trunk lock support
Spare tire bracket
Tail panel
Tail panel supports/fillers
Cross bar extensions
Jack brackets (trunk floor, wheelhouse & loop)
Rear valance
Rear valance hardware (nuts, bolts, etc…)
Rear valance brackets
Quarters
Doors (hinges, mechanism, & striker)
Deck lid
Deck lid hinges

Below are a few pics of what the car looks like now showing what has been removed.  Any thing I’m missing that I should order now so I’ll have it on hand???

Thanks!

Sean

I hope the projects goes smoothly.  You removed a lot of structural componets to have it on a roticerie.  Make sure you do a lot of measuring.  Good luck.

When it comes time to hang quarters, put 6 or even better yet 8 jack stands under.

That would be a good time to do the sub frame connectors also if you decide to. Do not do the final welds on the quarter until you are absolutely sure the doors and quarters are perfectly aligned. Then you also have the trunk lid and the lower rear valence fitments too.

Doing it again, the one thing I would do differently if I did it agin would be to glue the wheel well outer quarter panel lip to the outer wheel well inner lip. Heat from the mig is risky going into the skin.

Thanks, Burdar!  I hope it goes good too!  It was a lot of metal to be removed, but it had to be done.  I’m going to be a measuring fool before, during and after the sheetmetal goes on.

Thanks for the advice!  I plan on placing everything with clamps and sheet metal screws before any welds are done.  That should let me tweak and get everything perfect (or at least darn close). 

What kind of issues did you have with the outer wheel well housing?  Did the heat warp the sheet metal?

I used a Goodmark panel because thats all there was available when I bought it. I had to make many corrections all over where ever there was contacts to the innner structure.

The main problem with the wheel well was that the gap between the outer wheel house I replaced (which was dead on where it needed to be like the original) was having gaps. I used small clamps everywhere. 

It was difficult to get the 2 metals perfect contact so that mig welding into both would be quick and easy. Burn thru was occuring especially at the upper top areas even though I was using twenty guage wire.

Based on this experience, whether it's an AMD or Goodmark, I would glue the wheel lips together. That way its sealed really good anyway. The rest of the contact points I could see mig weld or even spot weld. The way the factory did it with the tongs is by far the most ideal way I think.

Another area of fit was the back wheel well behind the back of the tire. I ended up needing to get a BFH and mooshing the 2 lips together so they would fit together.

Again, this was a Goodmark panel. Which never had any bragging rights on fit by others including myself.

A couple things else to mention:

Get the mig welder vice grips that have a copper pad on one side. Have a high psi air tip and wet rags. Cool outer metal with the rag while blasting with air right at the new weld.

Thanks for the info Mike!  I got Goodmark quarters too.  I heard that they made some improvements to the quarters about a year ago.  About the same time I ordered mine.  I'm not 100% sure if what I heard was true and if I got a set of the new ones or old ones. 

I just ordered some stuff from Eastwood a few days before you mentioned the vice grips with the copper pad.  Would have had them send one of those too!  Oh well!  LOL!

Good luck, take your time, and keep us posted.

Check online, you might find those cheaper. HF used to carry em and I bought mine for under 10 bucks years ago.

Northern Tool has the best price on them. Looks like HF doesn't cary them anymore.

Since mine is now finished;  here are some of the areas I had to modify on my Goodmark.

The rear window edge of the quarter had to be brought out. this was done so that the chrome trim hugs up close to the body without any gap.

The lowest corner curve on the rear glass sits had to be cut, knocked in about 1/16"

The quarter panel body line that runs parellel to the trunk edge had to be cut and lowered about an 1/8."

Still need to check the lowest fit at the very bottom of the rear valence. Looks close, but not as tight as I would've liked to be.

I would absolutely get it off of the rottiserie before hanging the sheetmetal on it.  There is no way of telling if there is any twist in the frame when you have it suspended from the ends.  The frame is integral to the structure of the car and any stress either way sets it off.  The suggestion of six or eight jack stands is sound advice.

I didn't put the quarter on while it was on the rotisserie. It was on jack stands.
Secondly, it had the U'S. Cartool connectors on prior.

I was just making a suggestion based on my experiences with body panels and frame members.  If you feel comforatable adding the body panels this way have at it.  I was only going by the pictures you showed with the car on a rottisserie and no body panels including the floor for structural support in the rear.  Good Luck.

I DIDN'T hang the quarter on the car when it was on the rotisserie!
This picture was AFTER it was installed then put back ONTO the rotisserie!

You must be looking at Sean's photos of his car on the rotisserie. We already discussed that issue in another thread:
