While we don't have replacement parts for a Model 70LP actuator, we do have a great replacement for it. Like the 70LP, these actuators are a fit for a 2" hitch ball, but they just have a slightly larger capacity at 7,500 lbs. You didn't mention whether you had drum or disc brakes so I'll give the options for both:

- Drum Brakes: Dexter DX7.5 Drop-N-Go Brake Actuator - Drum Brakes # 099-175-00

- Disc Brakes: Dexter DX7.5 Drop-N-Go Brake Actuator - Disc Brakes # 099-175-20

I've added links to video reviews of both actuators for you to check out as well.
