I just started one for a flyin Bud and the fire wall is only 3 11/16" wide and 4 3/8" tall.
This is the practical mounting area , are any of these gassers gonna fit?
The plan for this one is a Saito 1.80 and it's going to be upright to fit without some chopping.

What kind of mounting foot print do these have ? thats what I'd look at first.
