hi everyone

got back to working on my 54 1.5 ton and started stripping wheel cylinders on the front getting ready to clean and rebuild. i grabbed my handy book of partnumbers that my job was just throwing in the garbage and my front cylinders are not there?
to make a long story short i have 7/8 wheel cylinders and i have no clue what there off of my truck when i tore it down did not seem to be altered but hard to say with all dirt grease and rust. if i find kits to rebuild the ones i have does anyone think it will be a problem with braking being smaller?

thanks everyone who has helped me with questions in the past its nice to have a site where people will help
