All Need some help! I inherited an early / mid 80's VC Resolute III 0043 (two doors, not one). Recently I renovated a room and in doing so, raised up the hearth but didn't account for the change in stove pipe length. Genius at work I know. (1st pic) Anyhow, having trouble finding the approrpaite pieces to fit. I couldn't retrofit what I had as the top and middle sections of pipe were essentially fused togeter. 30 years of fires and self tapping screws will do that i suppose. Anyway, I bought a (6'') Dura Vent telescoping piece, alas the VC stove has an oval flue collar (2nd pic), and my stove pipe is round. Also, the pipe won't fit all the way over that crimped ceiling piece in the (3rd)pics below. I imagine I need some sort of adapter or trim piece to make this all fit correctly. Any advice you could all lend. Thanks!
