If it is anything like the Grant I did there are a considerable number of components in the suspension 14 per unit from memory, and each track consists of 79 links with 6 components for each two links, it may be worth building a jig to help with the track construction.hundreds of parts fitted and I still haven't tackled the suspension and tracks, they are individual links, about 79 of those, not sure how many components make up the suspension yet, lets see...I want to do the tracks before too many fragile parts go on the exterior.
