Peter, perhaps you should find out some more concrete information on the truck you're trying to sell...
First off, if this is the 'bushviper' truck, it was said in the past that it has a 'modified watts linkage' ... which from the pics you can see the arms from the watts linkage still, so I don't know how you replaced it with a steering part... but anyways, find out what modification was done, were the arms bent like the RTE ones? was it just notched out?
Also, HD front axle shafts, no one currently sells these for the D2... Ashcroft is coming out with them soon.. but nothing available yet.. so are these custom made, or do you not have them?
If you are unsure about some of these, such as the watts linkage, take a few pics and post it here.. watts linkage is in the back of the truck by the gas tank..
