Componant sizes and geomatrey

[LeonN]

I am looking for some sizes for boath frunt and rear sierra hubs. I canot afford the inflating prices of sierra parts and have a plethra of other components lying around. Though in order to youse I need to know whot I am trying to replacate. Are ther any mesherments and plans about for the sierra parts or indeed the entire suspencion setup.
Thanks.
