All EAs were 5-bolt with the bolt in (hollow) stub axles. I don't completely know the pattern, but they were definitely used simultaneously from the '90s until at least 2015 or so. I think in base model/small engine optioned cars.

Originally put this together for a friend, then realized it might be helpful to others wanting to do an STI swap. Basically everything you'd need to upgrade the drivetrain. Prices are roughly what I've paid in the last few months in US dollars. Yes you can use an automatic driveshaft and swap the flange from R160 to R180 but the STI driveshaft has significantly bigger u joints. If you find the right swap kit you can probably get a cheaper total price but I already had the trans. That's what I did in my black Outback, for instance just used the stock clutch and flywheel and only replaced the disc and release bearing. Can also buy a lot of these things from the dealer but they're more expensive. Conversely some of it you can buy on rockauto etc for close to used prices but I'd rather have factory parts for most of this. $2500 trans used 2006+ to fit our planetary low range $200 driveshaft used - get one same wheelbase as the car you're putting it in, 2007 STI seems to fit first gen Impreza perfect, got a newer one that fit my Legacy Outback. $715 diff used 2006+ $150 shifter used -2013? at some point they made the shifter longer I've been told $150 flywheel used but resurfaced $10 flywheel bolts (800610740) $8 flywheel pilot bearing (816212020) $12 flywheel dust cover (30216AA070) IMO required for off pavement use $6 pressure plate bolts (800508310) $450 clutch/pressure plate/release bearing Exedy FJK1000 from Rock Auto, looks like rallysportdirect is cheaper but not in stock $92 ACT monoloc from IAG - definitely optional $70 clutch slave used $10 clutch line 37250FE052 $23 clutch hose 37251FE030 $2 clutch hose banjo bolt 112925161 $2 clutch hose crush washers 114130151 $104 Trans mount 6MT 41022FE010 $75 starter used Probably not required but in order to run female front axles you need: $96 front axle stubs 4EAT 38415AA070 $5 front axle stub seals RF806730031 $5 front axle stub seals LF806730032 $2 snaprings for front axle stubs 805329010 Also since my car is an auto I needed: $35 clutch master used $75 STI pedals used (I think any Subaru manual trans pedals would work, looks like even Forester pedals would bolt in) Finally, you need one of the following: STI CV axles (rear at least), knuckles/hubs, brakes - can't fit 15s and are a larger wheel bolt pattern Slammo says "04 STi rear knuckles let you stay 5x100 and use stock 04 STi rear axles with an R180, and you can fit the WRX 2-pot calipers without adapters, but you have to use special rotors since the STi parking brake drum is a bigger diameter" but those 04 STI rear knuckles are rare. Suberdave's conversion races - maybe these would work OK on a lighter car if driven carefully but then what's the point? Definitely the cheapest route but at least moves the weak link to the axle which can be replaced in the field in a reasonable amount of time. Billet rear knuckles and R180 to front CV axle stubs - probably cheaper than STI knuckles, hubs, and brakes, and I think the best solution for reasons already discussed.

Thank you for the offer but I think I lucked out a fella is lookin to trade and he’s about an hour away from me just gotta check in on it

An old friend has his eye on it now that I’ve alerted him. He had the exact same color , model , pretty damn close all around to this one up for sale. Chris is a member here as well. This board is how we all came to know each other here in CT and just this past year I was sifting through one guy’s family’s barn and came across parts from Chris’ 1975 4WD wagon. That was a lifetime ago. Chris moved out west , started a family and now he’s back East. And looking for a match for his beloved 84 4WD wagon. And the stuff in the barn has finally been disseminated and concluded. Barn living a new life. Your story of the day. Cheers! Connecticut people can chime in now. chirp. chirp
