In the bottom of the gas tank. You may need to use a lighter to see it.
how do you take primary cover off an 86 sportster
Do you mean a Blazer? There isn't an '86 Tahoe.
My is a 86 and it takes 1.6l it says on your oil plug if you look close at it
Where is the drain plug for 86 nissan pickup
Assuming you mean a manual transmission, since you said gear oil, there is not a dipstick on manual transmissions. Look on the side of the transmission. There will be two large nuts to drain and fill. The bottom to drain, the top to fill. You should have your fluid level with the fill plug hole. BTW, I have an 86 F-150 4x4 5.0 EFI and the NP435 4-speed manual transmission.
Should be a plug on the side of the transmission about 1/2 up- fill to this point
