Some of you may remember the issue I asked about with me onselling an incorrect W - JZ bellhousing. I'm now dubious about whether the box I bought it with is actually a W57. I don't want to be putting it into my ae85 and finding out it has $$% up diesel ratios or something.
When I dropped the W55 I expected them to have identical casings/housings. Would this be correct? They are the same shape, but have slightly different 'lines' cast into them. Is there a way of checking without doing via ratios? I failed to get a photo last time I was at the car.
EDIT:
New box has a small, solid circle cast into the centre line somewhere along here that I first noticed:
Also, if you google image W57 Ryanfels' old gx61 comes up on page 4
