upgrade alternator

Im considering to upgrade my alternator to a IR type that delivers more AMP.

I have read about the wireing that needs to be changed, and it sounds like its easy enough..
BUT, i have asked and looked around in the nearby junkyards and cant find a alternator that fits, so it seems that i have to buy online.
And then i want to be sure that i buy one that fits and delivers enough AMP. (maybe 70ish)

Im after a alternator that is bolt on besides the wireing.
What alternator should i go for?
Is a Hitachi-LR160 a good option ?
Anyone know a part number or a place that i can buy one that is bolt on?

LR 160 is only 60 amp while the stock 510 was 33/35. Most later Datsuns into the mid '80s were 50/60 amp. These will just bolt on no changes.

The one wire Saturn alternator also bolts on. May have to modify the adjusting strap.

The Hardbody alternators retained the V pulley into the mid '90s. They are 80 or 90 amp. for a stable supply for the EFI. I have a 240sx KA alt on my L18 in my 710 sedan. Had to swap the V pulley onto it and splice in the two wire connector for the sense and charge lamp.

if your in the junk yard check out the subaru dl dg loyal and early legacy for the 60 to 120amp hitatchi and dont forget to take the T plug.

The wagons didn't have IR alternators though, correct?
So you will have to bypass the voltage regulator.
