Is the flex plate on my 93 Lt1 any different than any other year of Lt1 including the B body cars?

Also, is it any different then a normal small block Chevy flexplate?

In other words if I had to replace it what are my options??

 

its is a small diameter(153 tooth) flywheel for a 1 piece rear main small block, so, 153t 87+ SBC

 

Thanks!
