there she is DD. I think it was in a sunny wagon. not sure if its a h145 or h150, haven't had the chance to check.

So they are rare, i have never heard of one.

I know of 3.88889, 3.9, 4.11, 4.375 and 4.62(or maybe its 4.68?)in the h145/h150 range. Im so glad i had the clean out, i just figured it was a 3.9.

Would love to have 4.27 an excellent ratio for quick acceleration even in a street car.

47 on the crown wheel and 11 on the pinion, and it is stamped on the crown wheel.

4.27 is very rare. What are the two numbers stamped on the edge of the crown wheel?

hi guys, i was searching around at home and pulled out a 4.27 h150 or maybe its a h145 diff centre out of the cupboard. anyhow, i didnt know these were orginal. its in a steel casting with the small square like the alloy 1000 h145's.

i was just wondering if they were scarce or rare.
