76 TR 6 Trailing Arms

[Neil Beasley <74741.2020@CompuServe.COM>]

Hello all,

While balancing the rear wheels, I noticed the trailing arms on my 76  TR 6 look
like aluminum. After scratching the dirt off and even checking  with a magnet,
we concluded that's what they are made of.
Is this unusual? I keep hearing about corrosion in this area on the list and
always assumed they were made of steel.
