Welding the Front Quarter Fenders

Reading Time: 1 minute

Why get new ones when you can use 30hours trying to fix the old ones?!?!

I wanted to weld the front fenders rather than replacing them, even though I have two replacement fenders. Why is that?

  • Welding practice
  • Stubborned idiot like myself
  • Keeping the car more original
  • No need for respraying fenders since the other ones are blue
  • Replacement fenders have hole for antenna, and my antenna is in the trunk

So I got on with that, but I might replace them in the future if I’m not satisfied with the result.

So on to the cutting, and trying to recreate the corner, was quite painfully difficult actually.

So then I welded and this was the result:

It looks better than it was, turned out when i fit it on the car I needed to do a massive job with the filler, but after the result was quite nice. Good enough for now, might change the fenders in the future when doing a complete respray though, but then I will get completely new ones without old paint and stupid holes for antennas.
