Ibve bought a factory hardtop off eBay and although it has the brackets on the top I donbt have the ones that attach to the car (b72 Austin Sprite). Anyone tell me if they are the same as MGB items like these - http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=200388819780&ssPageName= STRK:MEWAX:IT Thanks. Paul H
