Shot in the dark. Looking for a pair of p4876124 valve covers

I have seen F-body, ( Volare, Aspen, Diplomat) suspension used. It is a one piece suspension. Torsion bars , stabilizer bar, Shocks, Upper and lower A-arms. All attached to the K-member. I had a scamp here with one installed. Drove and handled great. Also seen it installed in street rods.. Cheap, Durable and parts readily available. Also provides adjustable height.
I have a friend who used a Volare front clip in a hot rod truck. Agreed; It was a neat setup, the torsion springs gave him infinite height adjustment, however I am already set on using an Art Morrison GT front IFS. I've seen one on a 1940 Plymouth, and it sold me. That car takes corners like any modern sport suspension on the road today.
