Your gonna need a bigger hammer!

WD40 is ****e for removing corroded stuff .. Use Plus Gas, a drift and hammer.

Angle grinder and cut it off.

WD40 is for getting rid of water
Plus Gas or others are penetrating fluids

VINEGAR,,,,VINEGAR works ok ,soak it, leave it, soak it again ,apply heat,soak it again ,,,long winded i know but it works,,,,,,dave,,,,patience grasshopper, patience my son ,all will be revealed!!!!!

drill it out

thanx for your replies chaps, have spoken to my local garage, bit of luck a blow torch will sort it........if not cut it off and start again.

i had to cut mine off,they always rust in and do not move without lots of heat and a big feckin hammer!

Am I right in saying that the tow bar support and nut are on the tank side in a small recess moulded into the tank ?.

When I took mine off I had slip a 9" angle grinder between the bracket and the chassis to cut them free. Problem was then that I couldnt get at the cut off bolt with a punch to knock it out. ( cause of the fuel tank ).

In the end I welded a " kin " great nut on the bolt head and let rip with the nut runner until it came out.

Same happened with mine, ground off heads & bolts then knocked the bolts through with a big hammer. Now I got the issue of finding replacement bolts!!
