These won't clear my hood on the GT6 so I can't use them. It's a pair of nice aluminum velocity stacks that I got for my SU 1.75 carbs a while back. They have a dual bolt pattern, so not sure exactly what else they fit, but maybe someone else does.
They're in good shape, but have a few scuffs and (very minor) dings on them from being in my parts cabinet for a while.
a bit over 5" wide and a bit under 3" tall.
Anyhow, I don't even recall what I paid for these, so someone make a fair offer if you're interested.
They look to be similar to these but no idea if they're the same brand. http://wbclassics.com/content/velocity-stack-175-su-carbs
