Not sure, but there may be a street ell fitting that would allow you to connect a regular 45 and the street ell 45. Otherwise, a short nipple will do it. I would point out that you can not "dry fit" ABS or PVC pipes. These use an interference fit which prevents the pieces from bottoming out without the solvent being applied first. If you try to dry fit, two things will happen. First, you will play hell trying to separate the pieces and when you make the real connection, you will lose about 1/4" per joint. You have to cut and fit as you go.
