Like these?

The first picture is a 99-95 L19 7.4L with the stamped steel brackets.

The second picture is a 96-00 L29 7.4L with the cast iron brackets. These are much stronger than the L19 and allows for a much better A/C compressor and bigger 124 AMP alternator. I run these brackets and accessories on my Gen VI in my '78 K10.

You might be if you’re not running an A/C compressor.

You can go to your dealer and look up a 97 3/4 ton BBC truck and they can print a copy of the exploded view with all the parts and part #'s. I had a 72 454 in my 97 2wd 1/2 ton truck with this set up on it, and I got the idea from looking through the parts guys picts. alot of those parts are available through Autozone and March Pulleys, so I used aftermarket where I could and OE where I had to, sorry not alot of help there, the BBC is on a stand with no pulleys on it till spring (when the snow melts and it warms up!)
