Triumph Tls Wheel Front Wheel Alloy Rim

Hello, the project is proceeding but I'm trying to find a suitable alloy WM2 x 19 x 40 Alloy rim for the 8" TLS (non-conical) front hub. The Jones rims I've tried allow the wheel to be built but the spokes on the non-flanged side bend over each other when they overlap as the rim spoke holes don't seem to be offset enough to allow for the overlap. The rim should have a 2x2 spoke pattern (i.e. two holes on one side and then two on the other), rather than the 1x1 pattern on the Jones rim. Does anyone know who supplies the correct rim?

Cheers, MikeJ
