Gt performer/pro performer Taiwanese or Japanese ? Options

[shroud]

Hello all , slightly confused over the origins of a gt pro performer. I have read that if you have four holes in the rear drop outs that the frame was made in taiwan but these were not made there till 87. The serial on this says it is 86 , it is 1860069 with a fs stamped below on dropout and four holes in the rear drops. It has the gt 4130 stamp at the end of the top tube. Any solid knowledge would be very much appreciated. I have read that 3 holes on the rear drops means built in the us and four for Taiwan , maybe it is a japanese built frame? It was bought as a f/f with new powder coat , not quite the right shade of yellow. Thanks ;-)

you have a USA made - january 1986 - frame...for certain.

japanese frames use a different serial sequence and location (as did taiwan frames). taiwan frames didn't start til the later part of 1986.

Ok thanks mr coasterbrake, but what's the four or three hole configuration on the rear drops about, and is it full cro molly or part?
The welding is not that neat and I am afraid to hop or jump it incase I crack it!

i don't think the 3/4 hole thing has ever been definitively sorted out as 100% reliable because a lot of that old stuff was made with whatever pieces were available/accessible at a given moment.

that said, yours is full CRMO. all the GT USA made freestyle frames were. and yes, sometimes the welding is not so pretty - even on USA frames. (actually, the japanese stuff often was more consistent.)

Thanks again for your help ;-) cheers
