I'm replacing the clips that hold the rear leaf springs together. The correct terminology used is "Spring End Clamp Clip" (for mgb 1 3/4 wide).
NAPA, Autozone etc don't carry them, but I've found a online supplier.
I'm not sure how well they will work out but I figured I would pass along what I've found. They are a buck each, plus a buck for shipping.
fyi: It took me about 8 phone calls & a couple of hours of googling to figure this out...
The straps have a dimple that's opposite of what's needed for the MG, so I drilled out the dimple so the locating "bump" on the spring will hold the strap. Little bit of flat black paint.
