Interim update:
After 3 hours of searching, researching and measuring up/ use of The Force, I settled on some shocks:
Ofna 9.5 RTR fronts, two pairs from ebay; havent built any shocks in kit form for a long time, so it'll be nice to have aplay with them and choose the oil.
On that subject, any advice or part numbers on firm springs that will fit is very welcome- according to the specs the springs measure 16mm on the inside, 19mm on the outside- the kit comes with silver springs as standard I believe, which are probably soft I imagine, but we'll see how they feel once I have them with me in a week or two.
