Is it physically possible to re attach the rubber straps (especially the rear) back on the fuel tank or is there a special tool?

I had to remove the straps due to engine work. I had to remove the head due to crack in it and the front oil reservoir thus having to move the fuel tank.

I managed to get the front strap back on FINALLY... What a PITA especially having to lean in through the front with one bad shoulder due to recent rotator cuff surgery. I can not even get 1/2 the leverage on the back strap though. Temporarily or maybe permanently I have attached a ratchet type tie down to hold it in place and it seems to work very well so far.

Tools, suggestions?
