This part was never offered individually. It does not seem to be listed in the parts books. It is welded into two other parts. It had 26 spot welds holding it on. What's it for? Think where you have seen it before.

Front bumper reinforcement plate, normally part of the inner wheel well/ head light bucket

I believe Chi-town hit the nail on the head.

mud collector,,often rust through behind it

I agree 100% and that is how I knew what it was- sadly.

Boy that was quick. 100 % correct. Going to install them on the 75 for bumper conversion.

Wow, THAT is dedication.
Access to weld on the trunk side is going to be tough.
Are you going to remove the welded impact mounting brackets ?
I didn't. I felt they might come in handy to attach tow loops.

Don't know if this is any use, but I have lots of pics from when I did that repair on my car starting here: http://www.914world.com/bbs2/index.php?s=&...t&p=2625621
