Reply #1 – October 01, 2007, 11:12:30 PM the 90 lx would be a 4 lug unit unless not stock. i would have to say it will bolt right in to ur existing control arms may be different width im not 100% clear on the interchange of exact same deminsions someone else can chip in there. as far as the transmission goes it depends if you want a stick or auto if ur weekend racing involves drags then go with an auto.

found something need advice.... Reply #6 – October 02, 2007, 09:30:08 AM Chuck is correct. I forgot what year the switch over occured on the axles. My apologies. CougarBirds got the wider axle housings in mid 85. For some reason I was thinking 87. Again sorry:shoothead Quote Selected

But then I suck at rear-end identification :hick:yes, you do. :hick: my 93 2.3l had 3.45 gears stock. 3.73 were commonly used in the 2.3's, due to the lack of power the motor made. :hick: Quote Selected

Most of them at the yards by me have 3.73s. It's a cheap way to get 3.73 gears for your 7.5 though :hick: Quote Selected
