I've noticed Summit and other companies sell them. How do they compare to the 87 GN stock box. Is it considered an upgrade for these cars? If so, is there any one better than the other?
Thank you.
The 600 gear box is an upgrade to these cars and makes a drastic improvement over the stock box, add the DSE steering shaft and you will be amazed at the difference it makes! We sell Both if you're interested....
