Saturday March 15th. A busy day

 I had taken my Zetec Cortina differential to Herts & Bed transmissions in Baldock, Hertfordshire the previous Saturday for him to replace the crown wheel and pinion and also fit a limited slip differential. 

The crown wheel and pinion are a new item from Retro Ford and the ratio is 3:31. I've bought this in the hope that it will bring the revs down enough and I can avoid the huge task and cost of fitting a five speed gearbox. Calculations show that it will reduce it by 300 revs, which doesn't sound a lot, but is. (If you drive your car at 2000 revs, then increase it to 2300 revs, you'll see how much more the engine has to work)
I also purchased a Blackline limited slip differential which will also stop the accidental wheel spin that the car gives me in the rain as the LSD will provide more grip. 

I set out early and was at Herts & Beds transmissions  at 6.45am. Luckily, the top man was already there and after paying my bill and having a bit of a chat, I was on my way home. 

A trouble free drive saw me arrive at my friend Gavin's house in Wickford and after a cup of coffee, I left my car at his place and jumped into his Triumph and we went to the Billericay classic car breakfast meet. It was still quite cold, so there wasn't that many cars there really, but a beautiful Cortina Mk1 2 door GT had come down all the way from Bury St Edmunds. All of us Cortina fans at the meet had never seen this car before, but all agreed that it was a very nice car indeed. (See below pic) 

We spent a few hours at the meet, but left when everyone else started leaving. On arrival at my place, I changed into my overalls and went into the garage to refit my differential. It only took an hour or so to get the rear axle back together including refitting the half shafts and bolting the propshaft back on. 

I then refitted the back wheels and all I had left to do was fill the new differential with oil and bleed the clutch master cylinder. (I had removed it and replaced the seals the week before) By now though my long day was catching up with me. I'd got up at 4am and was doing my Saturday shopping in Tesco's Baldock at 6am. so I could be at the transmission place for 7am!  I was starting to feel cold as well, so I called time and went indoors.
