Easier than what, ordering the part?
The Belton is a BL3EB3C1B. If you can't find one of those, replace it with an Accutronics model :
4EB3C1B, 9EB3C1B, or 8EB3C1B
And if those are not immedaitely available, change the fourth character to a 2. A 4EB2C1B wil work fine and have an ever so slightly shorter reverb time.
