End can to headers gasket?=Loose can!

My end can is very loose and theres lots of space between where it joins on to the collector box! So checked out a honda microfiche and i need a gasket for here, which i now have- is there a procedure to fitting??? Damn thing wont stay in place when slipping can on and either falls in or gets squashed!

 

Got a pic? It may help.

 

To wrap this up- place circular gasket inside of end can. Its a real tight fit so remove clamp and space out the gaps with a flatblade screwdriver and push in at the same time!
Once in refit clamp and push end can onto the headers(another tight fit!!!) Tighten everything up and shes brand new again!!
