Defender Bulkhead swap TDI to TD5 ?

[Benny_IIA]

Hi Guys,
I have removed my very rusty firewall/bulkhead from my Defender TD5 (December 1999). I have been kindly offered a replacement from a TDI Defender. Can anyone please advise if this will fit and does air conditioning make much of a difference.
Many thanks Ben.

Hi, physically it will fit but you may have to re-use your original tunnel section as these are different (in the later TD5). Also you may have issues with the wiper holes which are round in the TD1's and elongated in the TD5's (the later ones anyhow). I also had to make new brackets to hold on the dash section near the windscreen. There are other holes which have to be altered, such as the A/C drain, new mount for the inertia relay, ....

also, any earthing onto the firewall, run an earth strap from each point back to the main earth adjacent to the rear of the gearbox.

At the end of the day, I have a TDi firewall in my 06 Defender, but I don't know how much changed from your Defender to mine - could be a whole lot less.

What what ever you do, prepare the new firewall properly to stop it from ever rusting again - I used a product called POR 15 (but there are similar products) - at $70 per litre this is an excellent investment.

The 06 Defender dash is different to the Tdi and early Td5,s , so that shouldnt be a worry ;)
What if one supplied the Tdi wiper spindles with the Tdi firewall:cool:

The wiper spindles from earlier models to the later ones have a different gear ratio and finish up wiping outside the windscreen boundaries - not possible to adjust. I have been there. The TDi wiper motor is in a different position to the 06 wiper motor, but I don't know when this changed - either in 99 or in 03

The firewall is from a 95 Tdi , i have a 01 Td5 the wiper motor is in the same position for both;)
