Seats are all done now. As I had the front holes in the right place i just made a jig out of wood and located the rear positions. I then built up little turrets in 3mm steel welded to the plates on the floor, which bolt in place.
We both got under the car with it up on stands and gave it a good chisle and brush. The underseal comes of pretty easy as its gone quite brittle. Luckily the floor is really solid! Still has the red primer in most places. I epoxy mastic 'cated?' the underside of the floor let that set over night as well as painting the brackets with it too. Very snazzy. Seats were bolted in place- so nice. No photos as yet of finished job.. I'm waiting for the right light...
The next day I towed Hannah in the viva behind our '84 1.3 racing sunny. We went to local exhaust guy who did a wicked job of piecing together a nice system out of pipe work and spare mufflers I had. I hate climbing in and out from under car on axle stands welding exhausts together with no proper bends. Glad to get someone else to do it. Put exhaust wrap on the down pipe as its close to the servo. Plus a M18 x 1.5 nut on down pipe so I can fit a lambda sensor.
While he built the exhaust from the front Hannah and I made the most of it being up on a ramp and with tools we took along scraped away as much underseal as we could- mainly at the back where it was thin. Some light surface rust on one side near spare wheel well but otherwise fine. I will epoxy mastic it all. leaving the rest of the underseal down the tunnel for now as its solid and intact. I think I might get it sand blasted later on.
Today whilst also sorting out the dud alternator I had bought I took the tank out, tipped 20 odd litres of petrol into sunny, scraped all the underseal off, discovered some mild pitting that I'm glad I found now.
I filled the tank with water to the top and drilled a new hole.
With tank then tuned on its end, hole uppermost and hannah holding it and filled it up till water came out of new hole. welding away...how do I describe it...booossshhhhh. Ther was till some vapours in there , like sod all but it shot through the pipe and weld leaving a 4mm hole. THis blew my arm which was across the tank up and over me. crikey! That put the jitter up both of us- turned me into the most paranoid welder. I just could believe the affect of such a small amount of vapour!!! It would have been no more than half a litre?
Ive now soldered in a new outlet pipe. 3/8. Now my new pump wont be sucking through a straw.
Noticed that it doesn't have a breather on tank- do vivas breath through the cap? What about HC vivas?
Also today picked up 6 meters of good quality cable for my boot mounted battery. Scrap man bargain- £10 woohoo!
