MG T-ABC

Anyone used this company before and if so their opinion please. Assuming the price list is current seem very competitive.

All I know is that they've been around for a long time, and I've heard mostly good reports about their products. Namely fuel tanks for various cars.

Treat with some caution. A stainless steel fuel tank from 'Metal Mickey' (not for an MG)would not fit and had to be returned. This was a few years ago so current production may have improved.

I bought a couple of inner wheel arches for my TC from NTG last year before I started to cut the middle man out and find the manufacturers direct (which I wish I had done sooner as I would have saved money).

From the look of the photos on the site that you have linked, this is where NTG got them from. The two bits of metal that make each were spot welded rather than seam welded (as on the originals) and I found that I had to do a fair bit of metal bashing to get them to fit the curve of the bull horn, outriggers and wood as the radius of curvature wasn't right in cross section.

Apologies to the company in question if this isn't where NTG got them from.

Note that the front quarter panels are fairly easy to make by shaping sheet metal to the wood frame. The original rear quarters can be recovered by cutting the 'tails' and butt welding new metal as long as the critical curve down to the top of the door is usable.
