Kodak Black says the Florida cops who arrested him for allegedly trafficking oxycodone are still holding onto his car and thousands of dollars in cash nearly a month later … and now he’s out of patience and wants it all back.

Kodak is asking the court to make the Florida Highway Patrol officers who busted him return a Dodge Durango and $74,960 in cash they seized during the arrest … this according to legal docs obtained by TMZ.

Kodak’s lawyer, Bradford Cohen, says his client can prove the car and cash belong to Kodak and were not involved in any illegal activity.

For starters, Cohen claims the Durango is registered to Florida-based record label Sniper Gang, and Kodak is a manager of that entity.

Since Kodak has already turned over the prescriptions for the pills found in the vehicle, Cohen claims there is no legal basis for the police to continue to hold the Durango and should return it pronto.

As for the roughly $75K in cash, Kodak’s attorney says he carries so much dough around because he’s a rapper and it goes with the territory … claiming Kodak needs large sums of money on him to pay various expenses on tour. Also, he’s often paid in cash for his gigs.

Remember … cops pulled Kodak’s car over last month and say the ride reeked of weed, prompting a search that turned up the cash and 31 oxycodone pills … this according to cops.

Kodak’s attorney claims he ended up providing cops with a prescription for the pills … and insists there’s no basis for cops to continue holding the car and cash as evidence.

The court has yet to rule.
