i just bought a 7mgte and r154 to swap into my 88 supra N/A. it had a 7mge and w-58 so i have the drive shaft from that and i also have a drive shaft from a 87 turbo with the a340. what i am wondering is if i can take the two of them and make it into a drive shaft that would be the right length and spline count for the r-154 to work in the non turbo car
