I'm new to amp building and my schematic reading skills are not up to par, I'm currently converting a hammond A035 to a guitar amp, I'm looking for a point to point wiring diagram, I have input output and power sections done, I want install volume and tone stack, any help would be greatly appreciated,

Your details are very lacking. Here's one successful AO-35 conversion by Dr. Z. It's called Carmen Ghia. Maybe you can use some of this to finish your conversion.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Here is another link on the subject http://revolutiondeux.blogspot.com/2012/01/dr-z-amps-carmen-ghia.html It is a small tight chassis. Difficult to work on and to get the noise down. So some (like me) rob the trannies and a few other parts and start with a new chassis.
Another amp that originated with that chassis is the Goodsell Super 17. I don't know if there is a reliable schematic for that amp.
