Hi mate, it depends what gaskets have been used sometimes the metal ones you may be able to get away with but they crush to an extent so for the sake of a few quid its worth getting some. eBay is always a good look,
These are ones I found quickly to give you an idea
Now Shagging sheep on the cheap
You wont find one that's for keeps
Spend the money, find a honey
'Shit' think I need to sell my Sunny!
But woman cant replace a sheep
Oh I wish that for the peace!
But I really cant find my honey
The only one I would give my money
Is one with a great big fleece
And then I would be at peace...
