Car seat help

Ka

So my sister in law is 8 months pregnant and I’m ttc! I’m watching her baby on the weekends so she can work, but I have a very small car. I have a 2001 Jeep Wrangler with a 4 inch lift and 35s tires so it’s tall.. it’s also a two door and does not have the latch system or a middle seat. I am only 5’1 so putting a car seat behind the drivers seat is not an issue. It’s a stick so I already sit close to the steering wheel. I do not have the money to buy a new vehicle and I love my jeep way too much to get rid of it. So I need help finding an infant car seat (preferably not a convertible car seat) that would fit! Any suggestions???
