Hi Gavatron,
Is the car L/H drive?
Depending upon the cost to have them removed, altered and then replaced, it may be an idea to look at another alternative.
You have the option of a set of Pacemaker 'Tuned' Length (4 into 1) extractor's;
PH 4010
MUSTANG (1964-69)
260-289-302 Windsor | Manual & Automatic
Note: Will fit C4 automatic.
Will fit with XD to XF integrated power steering RH drive.
Will fit LH drive with original steering box.
Will fit 4 speed Ford top loader gear box.
Will fit with Toyota Supra 5 speed gear box.
Will not fit with LH drive mechanical clutch.
Will not fit LH drive with ram type power steering.
Will not fit with GT40 Heads as fitted to 302W AU II due
to Spark Plug angle.
