Help me rebuild my dads jeep

My name is John, I’m a 16 year old mechanic   assistant. Over the past few years my dad and I were working on this 1998 Jeep Wrangler until my dad passed from cancer a year ago. since then I’ve been working on restoring this Jeep myself but lately have ran into financial difficulties trying to buy parts.  If you could help me in any way big or small I would be truly grateful. I want so much to be able to finish this project    That me and my dad worked together so muchon.

thank you! -John
