150mm nails, I have selected the corrosion resistant ones for you, you do not want this to go rusty!! https://www.screwfix.com/p/easyfix-exterior-nails-outdoor-green-corrosion-resistant-6-x-150mm-0-25kg-pack/84952
Bit of selotape will also help, I am sure you already have some in the house.
Get the new bars and hold them up where you want them to be, hold them in place with Selotape or a get a young child to hold them for you.
You are going to want at least two nails at the top and two more in the bottom and at least one on each side.
Get the first nail in at the top, it might bit a wee bit tight but this is why we have the 1kg hammer, a good few swings will get it through the bars and into the tank.
If it looks a bit high or if you need to move it around use the 16 ounce hammer for adjustment.
Once you are happy with the position get both of the bottom nails in, this should be easier going because the sump is only aluminium.
Final position adjustments then get the final top one in and both of the sides.
Again might be a bit tight but getting it in but a really good swing on the hammer will help and the ones into the engine case will be easier.
Word of caution, it the ones in the middle go in easy and then start to get tight you will need to move it because you are probably hitting the cylinder liner.
Pro tip, if you dont want to move it, it would look untidy with extra holes, start the engine and get a few revs on it and then hit the nail home. With the engine running it will chop off the top of the nail as it goes into the cylinder and you will not risk having the nail in through the piston or on top of it preventing movement.
Once it is secured in place you can use the 4oz hammer to tidy the nail heads up if you have not hit then squarely.
Repeat on the other side and away you go!
Always happy to help, no need for thanks.
But do remember, pictures or it didnt happen!!!
