Hi..some questions.

House is 22x75. Wanna install auto gate

1. Should i just buy a motor and keep the old gate?
2. If change..do i need to hack the wall sebelah the old gate..coz still got space

Im not planning to do the reno for car porch..was thinking i wan auto gate but any easier alternative instead of redo the entire gate section..

3. Can recommend me some good and affordable auto gate?

Thanks in advance!
