I've just put some (small pin eye - 15mm) extended shackles in my 1978 BJ40 and I want to get some longer rear springs to push the rear diff back, achieve a better shackle angle, thus better flex.
I've considered the abundant 60 series springs, but they are big pin eye (18mm), and I'm not interested in welding in some new mounts to take the big pin eye.
I've rang around most wreckers here in Brisbane and no-one seems to have FJ55's in stock, let alone springs. So I'm looking at alternatives - do the older FJ45 or HJ47 utes have (small pin) longer rear springs that I could fit into mine easily?
The FJ 45 and HJ 45 up to August 1980 use springs with the smaller eyes, not sure if they'd fit in a shorty though. Why not get a set of springs made up by a springworks? Also, there's no such thing as a FJ 47.

After doing some more research I think I might look into this a little more...
Does anyone know if there is enough room on the chassis hangar to fit the large eye spring?
Yeah it will fit, but it's a squeeze. I farked around with trying to fit 60 springs in my small eye fixed hangers with custom bushes but the military wrap used to rub pretty hard. While both early and late model hangers are about the same width, the distance between the pin and the bottom of the chassis rail is the issue, later ones are spaced down more to clear the bigger eye wrap.
I ended up getting later model 40 (big eye) hangers to swap mine with. Just a matter of drilling out rivets (PITA) and drilling/bolting the replacement hangers on. If you go longer rear springs, you're going to have to remove the shackle hangers to move them back/flip them anyway so you might as well just get big eye hangers to put back on since you're half way there.
Depending on the year, not all FJ55 springs are small pin. The later ones (75 onwards maybe??) had the big pins, but little eyes - ie 18mm pins, 30mm eyes whereas 60 series have 18mm pins, 35mm eyes.
Superior engineering sell cruiser hangers too if you want to go that way.
