Hi if you look at my public profile, In the picture you will see the roof bars, they were £160.00 from the dealers, they come in either black or alloy , I think the black ones are some £25.00 cheaper.
There are some here, some under £100. You have the option of a basket type, and 2, or 3 bars, plus many accessories. I'm surprised the dealers are so cheap though!
Find any Paddy Hopkirk dealer (we USED to be one!) and ask them for bars 401ul and a K07 fitting kit. This will give you two bars perfectly fitted into the likle black bungs on your roof!!
halfords do the bars and fitting kit, think it works out about £120.00. i found a 53 plate in a breakers called autosave in pimehole fold in bury manchester it has a full rack with rollers still on it. Not much help if your the other side of the country.
