1993 Mazda B2600 Looking Replace Recently Totalled 88 B2200 92 93 B2600 88

Am looking to replace my recently totalled '88 B2200 Mazda with a '92 or '93 B2200 or B2600. My 88 had a timing belt that needed replacing every 60k......IF the 2600 has a timing chain, does it need replacing at regular intervals or no?

Thanks much!
