Thanks for taking the trouble but would only help if I was installing a standard subframe with 10" wheels.

All I was hoping was that someone that had fitted a K series into the front of a mini using a Rover/Metro/MGF subframe could just measure the distance from the top of the rear rail to the underside of the engine bulkhead crossmember. Its just a reference really, I think it needs to be around 4 to 5 inches

Page 1 of my build shows how the Watson's frame fits.

In particular this picture.



The cross bar against the bulkhead on my frame was too tight. I had to address this with the lump hammer. Once fitted, it's never been any problem.

I would be really difficult to get an accurate measurement with the engine in place but can try if it helps.

No that all good fellas, bottom of the frame level with the bottom of the floor pan is roughly where I thought it should go. Just on with fabricating some new inserts for the crossmember ends so that I have something to bolt the end plates to so wanted confirmation

Cheers

I refitted my Watsons frame to my Mini tonight to get some other measurements so I measured this, my frame was slightly crooked by a few mm end to end but call it 110mm from the top of the rear crossmember to the bottom of the bulkhead crossmember. You probably don't need it any more but I thought I'd post it up just in case it was some help

Also worth noting that the bulkheads aren't dimensionally identical to steel Mini's, certainly the Midas which originally used part of the Mini Marcos in the development phase has a closer distance between engine and bulkhead that requires a shorter than standard Mini engine steady-bar, also the Midas bulkhead (top subframe mount area) is around 1 cm thicker top to bottom than a steel bulkhead.

Oz gave some good info on lining the bottom of the frame with the shell and is the best way to set the frame in place. In this position you will notice the wheels are further forward than a standard Mini frame. The amount would be dependant on what wheel size you intend to use. I suggest setting up a wheel, hubs and suspension arms to see how it looks with the front / wings of the shell in place. This will determine if some cutting of the subframe or bulkhead is required.
