Just got my rear trunk pan from Restoration Design to replace my rusty one. Need some help from folks that have done this before. The rear and sides look straight forward - just plug weld in place. The front is what I am afraid I will screw up. As seen in the pictures below, they gave me extra material (~5/8") to do something with. I would really like to avoid butt welding the entire front section if possible - my welding skills and patience are not quite up to it. Is there a way to plug weld the front portion also? It's a trunk that will be covered in carpet so I am ok setting my bar lower than normal




Edge of tape rear most represents where new pan extends to (but doesn't drop down to follow original shape)

There is a thread on this replacement in thr classics section

I did this but modified the replacement panel and butt welded the whole perimeter.
I cut out the heat shield standoffs so I could keep the shield intact. I pop riveted the heat shield using ss rivets.
Photo shows what I used (note some extra bits used for hell hole repairs)



Here's finished:

Cool, thanks for pointing me to your thread - a picture is worth 1000 words. Not even sure how you formed your lip to match the trans crossmember, but I know I don't have the skills to do the same. I think I will trim my replacement just before the raised portion for the crossmember, flange it, and plug weld the original.

I know how mine would turn out if I went the same route - horrible! I like welding but suck at it. Maybe someday I will get a TIG and get better at butt welding sheet metal, but probably not!

I only needed to replace the portion to rear of the cross member

That's exactly what I plan to do.

Thanks

Just because you have the whole panel does not mean you need to use the whole panel.

Only replace what you need to replace and grind the welds to hide the repair both top and bottom to make it smooth.

For the flange you can get a flange tool from harbor freight .

Not sure how I missed that when looking at their videos - thanks

That is what I did. They have slightly changed the pressing since mine I think.
