swivel replacment

hi I need some advice please I have just brought a front swivel kit for my 90 I opened the box and it appears to only have the top swivel pin in the kit is this normal?

I would have thought it should have both top and bottom pins as part of the kit, if it does'nt should i buy the bottom pin if I am going to replace the swivel

cheers

boittom is brg .which is all that needs changing at bottom the pin dosent need un bolting in any part of job,top pin is wearing part so is replaced with bush

hi James thanks for the quick reply sorry for bieng a bit thick but what does brg mean

cheers
