Fastland Bulkheads problem.

[maxxdude1234]

Yes, they are the hinge pins. They should fit through the bulkheads, and the e-clips snap on either end. (always have lots of spare e-clips, cos they like to go bye bye - like body clips)

As for the bulk design, I don't know (I have great assembly bulks). Silly question, but you don't have the 2 mixed up? - the front bulks have that odd little hole cut in them, and the rears are more like the stock ones.
