Are you going to use R-12 or 134-A?
You will have some problems,but it shouldn't be much.
You'll need a line set for the R-4 pump.
And,I don't sell parts on this site,so you'll have to post a want ad.When you buy parts,make sure you get all the correct bolts and hardware for the R-4 mounts as they are mostly all metric and very specific.Getting it all from the same engine at one time is best!
