just bought these shocks for my acme condor [link]http://www.sriremotetoys.co.uk/30222aa-upgraded-bottom-aluminium-shocks-pair-p-519.html[/link]

trouble is i thought they'd be a straight replacement but instaed of spcers for the top it comes with those two ball headed things which when i try fitting them there is to much play. the original spacers are to big and i don't wanna half arse fitting them cause i can't afford to have them break on me straight away. Any suggestions or a complete step by step idiot guide with diagrams would be much apprieciated

this is a diagram of the original ones for reference [link]http://www.sriremotetoys.co.uk/30221-plastic-shocks-wsleeve-spacer-sets-p-276.html[/link]
