This is a large (huge) webbed internally ribbered front sway bar D mounts
This 36 mm size is mainly on mainly '87 ON Trans Ams & Iroc-Zs.... you might want to check the bar thickness first...
This mount has a webbing surface inside to prevent easy wear etc (not that your likely to see it on an old D mount etc.)
This is for ONE. Order two if needed for a pair set. or look at the energy Suspension range.
Yes.. expensive.... GM originals.. also you might want to check www.energysusp.com.au. but these fit and the work...
