71 GTX Rocker Moldings - Help

Post by 71_bronze_gtx » Tue Feb 26, 2013 9:26 am

I have the opportunity to get these made from billet aluminum. They won't be exact, but pretty close.

I need a few measurements:

overall length

height

depth (thickness) at the top rib

depth (thickness) at the bottom rib

If someone who has a 71 GTX with the moldings could get me these numbers, it would be greatly appreciated.

This is a prime candidate for a mold. If someone could spray the molding with mold release and fill a 6 inch section of it with bondo and let it harden. Remove it and cut it it half, you have a perfect negative and most all the measurements to get a good repop. Just my 02c

Already had those pics.

Casting aluminum is not a simple process. The capital investment needed can't be justified by the number of moldings that could be sold - the price would be sky high.

Something close in shape can be relatively easily machined out of aircraft aluminum. In fact, I can get it done for the cost of aluminum and a lunch. Nice to work where there's a full service machine shop.

I have another friend / business associate who might be interested in producing a number of these at his own machine shop.

If a bunch of people tell me they are interested, I can go to him for pricing.

My plan is to make them stick-on using a double sided adhesive rubber strip. Looks like originals were screwed on.

Absolutely machining is the way to go, I just meant that the mo ld of the original will give your machinist all the measurements to work from.

That would be fantastic - thanks.

I'm ready to buy the aluminum and cutters required and have discussed options with the machinist.

That winter storm just missed us and is burying those @$$holes in D.C.

Should be able to bring the car home soon and get cracking.
