I currently have a 3:73 (4 speed), rear axle in my car with a 5 speed Getrag gearbox and I have a 3:45 rear axle from a 5 speed car. Question: Can I swap the ring and pinion gears between the axle housings - using the 3:45 gears in the 3:73 differential housing or do I need to swap the whole rear axle assembly? which would be easier? The 5 speed axle doesn't have brakes and I would need to swap backing plates, wheel cylinders, brake lines, etc so was thinking just changing the ring and pinion may be easier? Thanks in advance for your thoughts. Tim (pricelessjunk)
