Need help with Hank Aaron 715 HR ticket

I have the following ticket:

Manufacturer: Globe Ticket Co.
Type: Braves vs. Dodgers
Size: 1.5" x 5/5"
Dating: April 8 (1974)
Model: Adult Aisle 105

My question is, the ticket has an Aisle Number (105), but no number under the ROW or SEAT.

I was told this was common back then and the ticket is good.

Can anyone help?

Thanks, Tony
