When I was into nikes back in the day, I found the quickest way was to twist the throttle. Failing that a chain tesioner works quite well. 
Tell them about the bent treacle edges!

If it's gone really slack put a bigger sprocket on  I would think it's not so critical in a car application as there is no movement
compared with a bike swing arm. A sprung arm with a dérailleur type roller setup would be enough.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Remembering a certain TV programme that shall remain nameless, on that car the rear diff was movable back and forth by a small amount, any bigger
slack was taken up by removing links.
Just don't get someone else to hold the chain while you use a hammer to press the pins out...

Whatever you do needs to be very rigid, simplistically look at go-cart tensioning systems where you have the engine sliding on rails that are adjusted
with a bolt to push the carriage forward and clamps to the bed.
In your case it is probably easier to fix the engine solidly and move the diff.
You could slide aka go-carts or have a pivot, whatever you do it will need bracing between either end of the chain, think motorbike, you would have a
big fat swinging arm between the two sprockets.

Some diffs are pivoted in a carrier, some slide in a diff carrier, yours looks like it would be shimmed going by the photos in your gallery

If i was to shim it, would i risk over tensioning the top? Its the bottom of the chain that was too loose?

??? You can't overtighten half of a loop, the other half will simply take up the slack. As long as you leave the car in neutral (or lift the
rear wheels off the floor) then the chain will be free to rotate and settle.
