About 3 months ago I bought an 89 K5 and I was happy as a pig in sh!t but unfortunatly my jubilation wasn't a lasting one. Today I inspected the underside of the blazers floor panels and unfortunatly it's not a pretty site , it needs work and to be honest alot of work, This is my first truck and I wanted to do so much with it, I am just wondering how far I can take this thing and if I should just dump it the project. Basically it needs a tranny and thats going to cost $1800 for a Heavy Duty one with 12k Garauntee on parts and labor if it should ever die on me. I would need to fix the floor panels and the ext rust which doesnt look all that bad cept for the rockers and parts of the doors (small parts) In addition to the tranny I would have to lift it 4" and I would like to put 35s on there and eventually swap axles to a 3/4 ton. Is it worth it, is it really worth the time and $ to rebuild this truck?
