front aluminum cross bar question

[Chris Pomares]

Can a 76 turbo aluminum cross bar be added to a otherwise stock 69 front suspension? It looks like a few pounds could be shed.

Bolts right up...you also have to have the separate aluminum support struts. '69 A arms will slip right in. You're saving weight, but at the wrong end of the car.

You will have to update the protection tray to a late model one as the original won't fit. Gordon

i assume he is saving the trays weight also...

I think you need to run the tray, just for protection! The newer trays are much heavier so parts should be weighed if you care.

Thanks guys. It'll run a tray, probably aluminum. We're saving 80 to 100 lbs on the other end as it's going to run a 2.7 2cam4 POLO, aluminum decklid, licence panel, bumperettes, and hood on the other end.

I have been running one on my 69 racer for years. You might as well throw on some aluminum rear trailing arms on the rear also. Extra weight savings. BTW- I don't run the tray, never have and no issue.

I was under the impression the aluminum trailing arms caused the shocks to rub against the rear shock towers unless it was a 72 or 73.

It is easy- You just machine 25mm off the mounting point. It is threaded all the way. Been running my car this way since 2005.


Here is a good resource.

Also keep in mind the other benefit to Aluminum trailing arms besides the weight is stiffness. They do not tweak in high load corners with sticky tires on. Here are the weights of Al vs Steel- both are bare without bearings etc..
