mx73 and ma61 both share the f-series diff. centres and gears are interchangable i am sure. however not sure which cars came with which ratios.

All MA61 and MX73 auto's in Australia are 4.1:1

All Australian MX73's are factory auto.

i have just pulled a diff from a MA61 today and it is open center with 3:6 gears what else fits a supra?

Factory MA61's have either 3.73 or 3.91
Some Corona's and Celica's had 3.58

I'm not sure what you are asking with 'what else fits a supra' ?

As in a whole diff and casing, or just the centre?

the whole diff unit .. im sure the diff that came out is a 4;1..

MX73, MA61, MZ10, RT142, RA65 are all bolt in compatible.

While we're sort of on the topic, are all F series CW&P sets interchangable between live axle and IRS centres? Like can I use an old F series live axle 4.5:1 CW&P set from a Crown in an MA61 IRS centre/housing?
