Pinto Exhaust manifold spacers?
Upon fitting my exhaust tonight on my Lightweight, (mk engineering,) I have noticed a couple of things that could do with addressing.
The exhaust needs to be approx' 10 - 15 mm further away from the engine than it is. Does such a device as a pinto (thick metal?) exhaust
manifold gasket exist? (I hope that makes sense, I will need 4 of them, or one long thick gasket, to push the exhaust further away.)
I have moved the engine as far over as it will go now, so it’s this thick gasket / extender or nothing. (......... has fingers crossed!)
The second thing I now need is a different shaped pinto alternator mount. The standard one now would mount the bottom of the alternator through the
steering shaft! Obviously it needs to mount onto the engine in the same place, but the bit that accepts the long bar/screw for the alternator needs to
come out higher.
I'm sure I can't be the first person with these issues (maybe in our RHSC builds!) but can anyone point me in the direction of any
products / companies that make fat exhaust extenders/gaskets and different shaped alternator mounts????
Many thanks in advance,
Trevor.
PS - I will be at Newark Saturday morning, so I will trawl through the trade stands!

Not sure about the exhaust gaskey problem. Only this i could suggest is using a number of standard pinto gaskets to provide some thickness. The
standard ones are discreet gaskets. ie.e one per port.
As far as the alternator problem is concerned i may be able to help you. I had this problem on my car and as much as i moved the steering shaft, used
smaller belts etc. i couldn't get the clearance.
I am sure you will get many suggestions to use a daihatsu van alternator mounted on the opposite side of the engine, due to its size and power etc. I
decided that i couldn't afford this solution so had to think of an alternative.
The soultion i finally came up with was to make a 2mm thick plate to rise up the alternator by approx 1.25 inches. The plate bolts onto the block as
the bracket would and the the bracket is secured to the plate by bolts that i welded through the plate.
The bracket has to be spaced away from the plate to allow for the heads of the bolts that go through to the head.
Perhaps the best way to show you what i mean is to attach a photo:
Nope, can't find one. Will attached a sketch in a minute...

Have a chat with MK engineering. I had a similar problem with my xflow exhaust (fouling on the starter motor) and they gave me the number for a
company called Tube engineering (something like that) but I've lost the number. Top bloke who had 4 xflow exhaust manifold flanges sat on his
shelf, each one approx 8mm thick. I used a gasket between each plate and used bolts to put it all back together. Worked a treat and only cost a fiver
for each one.

If you have a drill press, then making the spacers is a piece of cake out of something like this:
