Those won't fit. The body is too short and puts lever behind side of gas-tank. Also due to lever hitting inside of gas-tank, the sealing surface won't match on bottom of tank and you'll have huge gap that leaks.
As you will find, there's very few "bolt-ons fixes" that will work. All require lots of labour-of-love, hours and hours of scrubbing, cleaning, cutting and welding. Shops are the worse as yutes working there that have no experience with anything older than 5-year old bikes. They don't even know what carburetors are, much less know how to work on one. It's like bringing in an 8-track or cassette tape and asking them to put it on your phone. They have no clue where to even start. They'll ask you things like, "
I can't find USB port on this tape?".
