Hi , yes , insurance company and DVLA will both be informed . Thanks .

you are legally required to tell them off the engine swop and a few other things to have you V5 updated. Otherwise it will fail its MOT.

That’s what I was hoping to hear Nick . I certainly would not go stirring up a wasps nest if not needed . Thanks . 

Those garage gnomes!

Yes haha! I think it will be around the same size or smaller than my driveshafts which is novel 

I’d be seriously wary of involving the DVLA.  That way lies huge pain and expense.   This is an existing, registered vehicle and chassis mods (as I understand it) are restricted to a few tabs welded to the main rails with the basic structure unaltered. So long as you have your 8 points (may be tight?!) and your insurance company are informed, you should be good. DO get it MoT’d though!

Ooof…. Is your diff one of the long-nosed ones? Propshaft is going to be REALLY short!

I see your point, but I am aiming to install the 6pot 6-8inchs back as to avoid having a bonnet bulge. With the mx5 gearbox attached I’m aware this is not possible without major chassis modification, which is exactly what i intend to do. I will be cutting the chassis rails just in front of the bulkhead and just behind my gearbox mount and removing the 6-8inch from behind there and then re splice those same sections in at the front if that makes sense? I’ll of course have to modify the body to suit. not much on my triumph is original and it’s a cheap car that I brought back from the dead, so I don’t mind chopping it up and having some fun with it, I’ve learnt a lot more this way than from my 4 years in college ‘learning’ about mechanics 

Your bell housing may be a bit shorter than mine, but I also think you are basing everything on the 4 cylinder engine position which may come back to bite when you fit the 6 as the engine/box joint is 1” further back on the 6 pot.

Yes it’s far more than I anticipated. Doesn’t make sense for the average driver to go for the conversion in my opinion, but for some reason I just really wanted to do it, so I did
