Help sizing for a new crown

[sweeney90]

Evening all

 

Sorry to ask such a basic question but I have never purchased and fitted a new crown so I really am having trouble with the measurement side of things. I have measured my current crown and the dimensions are as follows

 

4.88 width

3.61 length

The thread it fixes onto is 0.85

 

The trouble is I have looked on places like eBay and can’t find replacements with these exact dimensions. Would I have to buy a bigger or smaller crown and do some modifications or is it just a hunting game when I keep looking until I find an exact match???? I’m a complete newbie and any input would be greatly appreciated

 

Cheers guys

You will have to get whatever is closer. Other variables are the style, where the waterproofing is, case tube size, etc. Yes it's more complicated than it seems but if it's something simple and no pretense of perfection, something will fit good enough. Material houses may have more selection than Ebay.
