So, Joey MacKay, aka Gaboon, is putting together an A555/A520 hybrid & came across this problem which maybe a model year problem???
In the pic below, the A555 intermediate shaft is on the left & on the right is the A520 shaft. He thought he had an '87-'88 A555, but then again, does he? Is the A520 an '87-'88 or is it an '89 or ???
Thanks for the help
