Hi First post on Blatchat and nearing the end (hopefully) of my 420R build which I started in July. So hello After having researched various, very helpful build blogs both before and during the build, from which I created a mental sh1tlist of the areas that were likely cause me some grief, I considered my self to be fully prepared. I have been building single-handedly and in a single garage, which was bound to throw up some challenges anyway. I had anticipated that installing engine/gearbox on my own would be be an issue due to bulk/weight, lack of maneuvering space and the tight fit in the chassis. In reality with the alternator and throttle body removed it all slotted in with remarkable ease. Nightmare big bolt at top of LSD casing? Ground a chamfer on the end, plenty Copaslip. couple of hammer taps. Not a problem. These and all other areas of concern were seemingly behind me. Or so I thought. My car is an S3 with lowered floors and yesterday with all Sunday to play, I thought I would treat myself to an easy day which would show much visual progress and make me feel good. Three words - Tillet f***** seats!!!! Six hours in (just on the passenger side!!!) and still unable to have completed a seemingly simple 4 bolt exercise, I nearly gave in and put my spanners on ebay. I could choose whether I wanted the seat to pass the harness mounting brackets OR to sit flush to the floor OR to line up with the holes in the floorpan, but it seemed I could not have all three. At 10pm, for some reason I still cannot explain, the seat dropped into a perfect position. All bolts were threaded in from underneath and everything was good. For a few moments. Until I nipped up the last bolt - and spun the rivnut in the runner - and the bolt has loctite on - and it wont unscrew - and I am tired and I am unhappy. Tonight I will either grind off the bolt head with furious anger and start again - or maybe I will just go for a pint. What an absolute b!tch of a job. I just had to tell someone. Thanks for listening.
