Where in Tas are you located? Im grow up Hobart area, moved to mainland about 8 years ago
Member on here 'chinna' is up Launceston way, Im pretty sure he MAY be able to help you
Can you provide pics of damage?
By far the cheapest option is to find a wreck and buy that for spare parts.
Otherwise, actual individual parts like guards are getting very hard to find.
Stock parts for replacement will be easiest and no experimenting or dodgying up required!
If you have smished up your front headlights, I will send you a set and all you pay is postage. (from Canberra 2600 to your loc.)
R31 Swaybar will fit, need to fiddle with the x-member mounts a bit and you'll be fine. There are a few dattos (liek 1600, and Stanza etc) that have very similar front end geometry, so you may be able to get a tension rod/castor bar from one of them.... bit of messing about finding it though!
