How to play my ipod music a 1991 truck?

I have an old truck and an iPod touch. The truck doesn't have a USB plugin, it just has an am/fm radio. Is there a way I could play music from my iPod in my 1991 ford truck?

Will the transmission need replaced if he changes the motor?

My dad has a 1964 Ford Galaxie 500. Right now it has a 351W motor. He wants a 390 (original motor to the car). If he was to change the motor, would the transmission need replaced too? The rebuilt transmission has less then 20k miles on it since it was rebuilt.

Meguiars carpet and upholstery cleaner left spot on seat when removing coffee stain?

My wife spilled coffee on the seat of our 2014 Kia Forte with gray cloth like seats. It's not the velvety like cloth, but that nylon fabric like cloth you see in Fords a lot. It took out the stain, but left a larger one that looks like a permanent damp spot or waterspot looking area when it dried.

I did a test about the size of a quarter in an inconspicuous spot like the instructions said, but the spot wasn't visible enough to pick up until I used it on the stains. Is there any thing I can do to salvage the situation?
