Thanks for the info everyone!

I realised I did flush it out when I had the box out and bolted it up to the 304. Its been getting noisier and noisier for the last year. A lot noisier now, but what the hell. Ive driven it to Woodend and am actually here tonight doing a night shift. Then off to see the boss tomorrow. After this car show I think Ill pull the box out and get it to the gearbox guy over the road.

Meeting at the bakery Sunday morning sounds good. Maybe 8ish?

Sorry forgot to mention its a supra 5 speed, not an M21/22.

Cheers.
