It should just be a standard Square taper English bottom bracket I can't imagine them using Ashtabula cranks but it was a lower end bike so it is wholly possible in which case I am unsure of what to do (since I have never actually worked on Ashtabula cranks and don't have much knowledge or care for them)
For square taper cranks you would just need to figure out what spindle length and taper (ISO or JIS) you need and that would be dependent on the cranks you get (and generally manufacturers tell you what they recommend for length and what spindle it would be)
