Westfalia roof toggles, best place to buy?

I'm after 3 off Westy roof toggles, the ones that hold roof down when closed & also hold the bed up when roof is open.

I've read previously that some aren't long enough etc. so who has replaced theirs, where did you buy them from & were they any good?

Thanks in advance
