MGB & GT Forum

It doesn't look like it would be THAT hard, but would still like to see how somebody else went about it.

I've already started on, but not satisfied with the way it's going to modify a later GT fender to the wider gap between grille & sidelight of the early car (and I'll STILL have to replace the rusty lower section).

I *just* picked up a really nice early roadster fender, but I'll have to modify it to fit around the GT's A-pillar and cowl.

It's some consolation that trying to make a GT fender fit a roadster looks like a harder road to go than what I want to do!

Has anyone come across a video/discussion where an MGB fender was modified to fit an MGB GT?

Thanks for any insight.

I did one recently - roadster to GT fender conversion. Fairly straightforward, measurements should be fairly precise - pay special attention to the fore-aft alignment in particular. Cut the metal away, leaving extra on the fender for adjustments. Once you've got that sorted out, carefully weld a strip in to mount the weld nuts onto. Finally, add the weld bead (moss 457-990) and the weld nuts. That's from memory, and I don't have many pictures - however I'm no expert and managed to work it out without many issues. Have extra weld bead on hand, it's a challenge to bend well. At least it was for me.

XLNT! Thank you!!

It "looks" easy enough__and that's what I think scared me, lol

I ALREADY have a full ( 66" ) length of the bead on hand, so plenty of opportunity* to work that part out, plus I *saved* the bead off the old GT fender by drilling out its spot welds to have a rigid GUIDE of the contour.

I was tripping over myself trying to decide to leave enough material to BEND a flange (and then HOW to bend it) versus welding it on. I like your welded on approach!

Again, my thanks for throwing me a hand to get over this (most recent...) hurdle.


Getting way ahead of myself here, but seeing how A LOT of finished cars exhibit minor cracking and corrosion where the bead joins the body, I was planning to apply a THIN piece of 3M Butyl Rubber Strip Caulk (pt # 08578) when final fitting of the fender to body. Forcing a smear of the caulk under the fender side of the bead too, to keep any moisture out. Just a suggestion to anyone that's at the painting stage.


* I wonder if using my induction heater will soften it just enough to make bending the bead easier; again, plenty of bead to experiment with!

interesting as roadster fndrs are everywhere gt not so much
