Will an offset of 35 make a difference if the offset is supposed to be 39? Also would there be a noticeable difference if the tire was 185 60 15 instead of 195 65 15? Just wondering if I should hold out for the right dimensions? Thanks in advance.

That will jut the wheel out 4mm extra. Which will be no problem. The tyre is 10mm narrower which will make up for that. For reference im running 32 offset on my toyota which came with 45.
The tyre will be sligtly smaller so you will be going slightly slower than what the speedo says.
Id go for it and just use the correct tyres next time.

The calculator sez they will be 1.26" smaller in diameter.

The results of the changes you mention will be: 1. Your car will be geared down by 5% (the max permitted for a WOF) although seldom noticed) 2. If the new tyre size has equal or better handling characteristics to the original tyre, then you will be able to corner faster because of the lower profile. 3. The outer edge of the rim will be out from the centreline of the car by an extra 4mm which probably won't rub on anything. 4. You won't notice any change in the steering/handling of the vehicle due to the offset change, since you have to go more than about 5mm before you start to notice changes. Remember the offset of the front wheels sets the positions of the wheels relative to the suspension and thus determines the scrub radius. In your situation the scrub radius will become more positive if it's an old car or less negative if it's a relatively new car with ABS. Cars with ABS are designed with negative scrub radius.

Just remember that offsets can be either negative or positive but your diff of 4 mm will not matter if its either way .
