I bought my 70 Scout 800A almost 5 years ago and have been hooked ever since. Lifting options are usually 2" or 4" spring lift for around $500 (not much more than anything else). Another alternative is to go SOA. I've got a GM Dana 44 front and a IH Dana 60 rear but need to pay off some bills before I start the SOA. That 78 SII has Dana 44's front and rear w/ disc's up front. Lockers are pretty much standard for any of the Dana 44 axles found in all trucks. Parts are pretty easy to get as long as you don't go to Checker because they have no clue what a Scout is and think it was made by Ford or Dodge. The starters and alternators are standard chevy parts = found everywhere. Napa and Auto Zone have (or can order) any part you could need for a Scout. They are excellent 4 wheelers right out of the box. The 345 is the same engine in the Old School Buses and Dump trucks. Low revving engines with tons of torque. If you've got the $ that Scout looks and sounds like a pretty good deal. Every so often you can get ones for free but those take a lot to get them road worthy. I took mine to Moab in April and it did pretty good for still being stock (but has a 2" body lift). I am running 33x12.5r15 MTRs and love them. The only problem that I had was off camber problems w/ the carb but we got it running much better w/ a vent baffle kit. Mine has not left me stranded yet (knock on wood). Just beware that if you get an IH you will probably end up with a ton. Let me know if you have any more questions.
Thanks, Brad J.
