I have a 86' Volvo 360 GLE 1.7 which for 2-3 years wasn't started up, because the kardan (transmission tube, don't know how to say it in english, i'm from croatia

The problem is in the "teeth" where the kardan and the rear axle connects.
New kardan is too costy, some solutions?
P.S. Obviously, it's not my only car, I thought it will be great to convert it in a free (or very low cost) drift machine. Please give also some recommendation what to do for the best lo cost drift conversion.
Thanks and sorry for the crappy english.
