B61 rear spring U bolt casting,single axle

[skydawg]

The casting that positions the spring clips and center bolt is always wet and full of rust/scale.Were there originally rubber plugs or grommets to keep this bowl dry?

not that I remember  were there any plugs

I have never seen any factory looking part that filled those holes. I used a building construction product called Zip Tape to keep the water out on my truck. It is about 4" wide, very sticky, and weatherproof. My frame and springs are black and the tape is too, so it made for a fast fix. The tape will hold paint if you need a different color.
