need a 75 ohm digital coax with a 90 degree right angle plug vs RCA cable

I need a digital coax cable with a 90 degree plug on one end, and regular straight plug on the other for a specialty application.

Length of cable can be anywhere from 4-8 feet, not picky.

I see plenty of choices for regular phono/RCA jack cables, but do not see any options for a digital coax 75 ohm.

Does 75 ohm really matter for a digital coax cable or would a standard RCA cable be just fine??

I have seen elbow connectors that are a right angle and you plug that into an existing cable. Don't want to do that.

I have thought about cutting off an existing connector and having a 90 degree soldered as one possible solution.

Any thoughts and help would be greatly appreciated!
Thanks much
