First, it has a little difficulty when starting it when the engine is cooled. After running it for a little for a little while, it will crank up easily. Could it possibly be the battery since the guy i bought it from had installed a larger battery?

The gas hand does not work, but all other gauges do work well.

Transmission had been rebuilt, it is a manual trans., but sometimes grinds while shifting gears when the engine is warm.

And the last, pulls slightly to the left, but i think that it just needs to be re-aligned.

Any suggestions will greatly help.
Also, i have checked the tires and there are no knots or uneven ware.
