Primestar Dish Question

[osu1991]

Can anyone tell me if there is a difference in the length of the arm and lnb holder on a primestar 75e versus a primestar 84e dish. I have an 84e dish that was missing the arm and just found an arm that says for 75e dish.

Thanks

yes there is. Each dish size has a different arm length

Between a 30 and a 36 isn't much (couple inches) but it would hinder reception is not set up properly
