hey bud i was on here about three weeks ago trying to find out the same questions. at the bottom of the marlin store page there is a for "tech how to". it has most of the info you need. unless you have some buddies to help with the list you need to read these forums about what you want and do your research. other wise buy a 79 to 85 front axle the less stock stuff on it the better and by a kit. i have made most of my brackets but if you have the money just go buy a kit. it has every thing you need. then you have to do the back. level it and go cut off some chevy leafs from the rear of a 88 to 98 chevy. read up on the stuff i am talking about and you will find what you are looking for.
Some helpful advice,
questions like that rarely get answered do to all newbies even me ask them everyday. try doing as much research as possible. the straight axle swap is as common as wiping you a#*! so there is plenty of info. look up anything with SAS.
Hope this helps
