The gearbox guy wants me to order the parts.
 
I go to http://www.toyodiy.com/parts/p_J_1990_TOYOTA_COROLLA+LEVIN_AE92-ACMXR_3301.html to get part number 
04331-12091

 I go to https://www.toyotapartsdeal.com/oem/toyota~gasket~kit~transaxle~overhole~mtm~04331-12091.html and cant get a match to my gearbox.
 
Is there any easy way to do this? Is a kit available somewhere?
 
Thanks

Use megazip.net to find your part numbers.
I found kits are expensive in comparison.
Best to contact Terry O’beirne (Facebook Mr2 parts for sale), who likely have your parts and advice on what’s needed. Sometimes extra things are “best” done whilst doing the gearbox though may not be needed now or on your gearbox builders list as they deal with other gearboxes.

Megazip is great. I can't find an MR2 facebook page with Terry O’beirne as moderator. 

Sorry, to clarify terry may have a response to other posts on that page (not a moderator).
Look up his name and his standing in front of a car, located in Brisbane area. Hope that helps.

Thanks.
I've found the guy and sent him a message.
