Just trying to determine the differences. My 84 has the LSD but it's a bit noisy and I fear may be on the way out. Not the normal moan during turns but a "vibratory" sound over 60 mph. You don't feel any vibration...just the sound is like a harmonic from vibration. Also tends to spin one side only on occasion and I know the previous owner had it rebuilt by someone like Maaco so I don't have alot of faith. Going to put fresh fluid and LSD additive in to see if it helps. Anyways, know very little about pumkin dimensions flatty vs. widebody and axle/torque tube spline differences but are there any interchagable parts? Have tons of 87-89 rear LSD's from widebodies and it would be awesome if I might be able to rebuild my flatty LSD using a donor widebody diff (and no.....I'm not doing a 5-lug swap
I have access to 3 real flatty LSD's but all 3 cars are plenty restorable and I don't want to start parting good cars.
You are the same as me but worse! I wouldn't switch to 5 lug either on a flat body. The 4 lug is lighter and more nimble to drive. The handling of the car seems more precise on my flatties. I guess it is the light weight more so, but I wouldn't want to change anything on the 3 running flatties I have unless I want to experiment, which I plan to do on one.
I am holding a car without taking parts from it too. I hope to someday put it back on the road, or sell it to some one who will. The engine runs fine, but it needs springs and struts all the way around, and all steering components replaced, including the gearbox, coupler, ps pump and lines.
As for the rear end, I plan to swap in an intercooled '87 rear and TT into my '83 daily driver for better snow traction. I'll be sure to post about it. I might lose a little of the precision handling since the '83 is non LSD and very light. It is hard to explain properly, but the flatties rear seems to follow the front easier for better mileage. My widebodies stick to the pavement better for performance handling, but the flatties are nicer for every day driving around town.
