" From: <mail@xxxxxxxxxxxx> " " Mark; Congrats on the 4.0 swap. I am assembling parts " to do that myself but will stick with a carb intake. " Anyways, I have a set of 69 Jav V8 springs sitting " next to a set of American I6 springs. They sure look " the same except the Jav springs are about 2" shorter. " I test fitted the isolaters from the American and they " fit the Jav springs perfectly. I dont know what the " will do on the car, but if anyone has some input lets " hear it. When I get a week-end to spare I will swap " them to check out the fit......Russ but v8 springs are considerably stiffer; you'd expect them to be shorter so that they give the same installed height. having said that, i thought i saw specs for early jav rear springs that showed 1" less arch than american ones. i've wondered if it was a typo, but maybe stock jav springs are an easy way to lower your american? ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
