what middle 2 bolts are you talking about?
After swapping the axle flange and rear diff cover, the "newly" acquired diff still refuse to be mounted. 2 bolts at the front and rear cover bolt are nicely alligned but the middle 2 bolts are not. It misaligned about 5mm.
So am going to drill or elongated the hole further 5mm on the rear subframe, kind of like the gearbox subframe mounting can be move to front or rear. This way i can reinstall the stock rear diff if need to. I hope this will solve the problem...
What do u guys think about drilling the hole? Hopefully it wont weaken the subframe...

Dan,
That's a good question. It was taken from an unknown BMW rear subframe. It's a 3.64. Which i believe could be from e34 M20B25?

OK, got the rear diff fitted this morning (in Kuala Lumpur)..(eventually).
Tested drive, it's not that bad. at 5th, 100km/h, the rpm shows 2200rpm (i expecting around 2500rpm). Felt the engine lesser stressed.
I think it's not that bad, because of the *731 cylinder head on the M20B20. Of course, B25 would be the better.
So next project, either B25 or forced induction... not too near future though.
Thanks for helps/input...

Stock tyre size is 205/65/15. I am thinking to use 205/60/15, would this upset suspension system since now the overall diameter is shorter?
