				Deciding where to mount the engine & trans. Issues.
			 
			
			So getting back to this thing. And to add to the confusion. lol. Ive got a dummy engine bolted in the car using the front cover mount, and a 13b trans bolted up to it held in place by a jack-stand. My 1st question is: Dose this look right? Is that the way the mount goes?  But the answer to that question probably doesn't matter because for one thing, I plan to fabricate some engine mounting points for a 13b, and also because the way the trans doesn't line up the way I thought it would. This is the way the trans mounting location looks.  The left side of the picture is toward the front of the car. Is this right? I have a junk 12a trans for reference. And the trans mount holes are about the same location as the holes on the 13b. 21&1/2 to 22 inches from the front of the trans to the mounting holes. Similar dimensions that are the same on both transmissions are: Front of trans to output-shaft = 32" The only thing different is the shifter location. From the front of trans to the end of the shifter socket: On the 13b = 34", the 12a = 33". Picture of the shifter hole.  I kinda knew that the shifter location would be off. But I thought that the trans mounting location would line up. This is the engine location with that mount. Looks like a good location.  So I got to figure out where i want this thing and what to do about mounting locations. I want to fabricate engine mounts for a 13b. I thought I could use / want to use the stock location for the trans. Other considerations that go along with this are the: Drive-shaft: Use an FB or FC or Custom? And while I'm at it, do I change the differential to a independent suspension type? Also, what about an oil-pan? Ugh!
