yes it is, we just completed one for a customer at the shop, and are in the process of doing another for an FJ62 with the same problem. We have a very clean 76 frame available right now that has been sandblasted and powder coated and is ready for the swap. We can perform the swap for you or you can purchase the frame and do it yourself - if you are interested PM or call me at the shop. The good thing is we are relatively close!I've located a 71 that is complete but apparently has bad rust on the frame. I've not been able to look it over but I might this weekend.
I'm familiar with frame swaps on series Rovers-is the 40 similar? Is a frame swap something common?
