This chip is for an 86 L69, but I used it in my 85 LG4 with no problems. I did have to Dremel the plastic on the chip a little bit to get it to fit into the slot for some reason, but it fits fine and works great. I had it in the car for about a year (Actually it is still in the car), but the computer isn't hooked up anymore. It does make a little difference at the top end, nothing huge, but it was noticeable. $40 shipped if anybody could use it.

Thanks,
Eric
