Wondering if anyone knows the sizes of all the parts for the tb bypass mod. Don't want to pay 16 dollars for parts that add up to like 5 just not sure of the size of the dust boots and the sleave to connect the collant lines

 

I was able to find a brass hose connector at Home Depot for $2. Can't recall if it was 1/4 or 3/8, but you can always return it.
