if its an SCX10 honcho I can easily help as I have the kit form, and the links have their length printed on them

Rear lowers (this is just the metal part not including the eyelets) are6X106mm's
Fronts are 6X98
the tops no idea as there is no markings on them, but all 4 are the same length
Wish I knew where I put my micrometer as I could have got you the whole thing
