They have welded spindles and the engineer that i use will not pass them, you need to have a front end fitted with the standard spindles, i also spoke to the guys at red9design and they use a 1500 beetle spindle that has had the steering arm machined off and a bolt on one fitted, i think you might have a problem engineering that, I asked both mendeola and red9design for the welding proceedure and the code that was used to weld the components and only red9 came back with the necessary paper work, you also can look at the eyeball engineering front end as it use's standard spindles.
