Just use your LA bolts, be very careful about the bolt length, there is a threaded hole in the front timing cover, if you put too long a bolt in it, it will crack a cylinder wall.
Every situation is a little bit different ( bracket mounting for Alt.,P/S, A/C, etc. ). A good rule of thumb that I always use is the 3/4" thread engagement rule. Measuring thread / blind hole depth is always a good idea also.
