Try X-Factory (beside Millenium, behind GT Auto)
But things you should consider before doing.
- A spot welded or tack welded car is illegal and liable to be "sita" by JPJ. (because they have reason to suspect your car is "kereta sambung")
- During collision accident, car crumple zone is deleted. All the impact force is transfer into the passenger cabin.
- After accident, the car damage is much more severe than non welded and hi chance of chasis warping. (also because all the impact is transfered all over the car body chasis)
- Once welded, cannot be undone. Sure kantoi at puspakom checks.
