heater/coolant pipes

[Viper Stuart]

bit of a long shot but before I start phoning across the atlantic I thought I would ask here. there are 2 metal (I think aluminium) coolant/heating pipes that run just below the passenger side valve cover that feed the heater matrix. both are held in place via 2 spacer type brackets fixed to the valve cover and mine is leaking at one of the brackets. does anyone have a spare or know of the best way forward. I don't know if I could get it repaired by brazing ,or could just cut out a section and join with a rubber heater hose (I think 18mm will do the job). I would prefer to get the proper part but fear I may struggle

thoughts,suggestions??

thanks for your help Mark,really appreciated. I see the posting you started on the VOA forum and I may add to it with a picture of my mine as the heater pipework diagram doesn't look similar but will check when I get home. as for sourcing the part(if available) is my best bet Partsrack or Chuck Tator?
thanks again
