Default Allspeed Subframe Spacers/Pads Needed?

Upon trial fitting my allspeed subframe into my 1994 rover mini I've run into an issue where the subframe looks slightly misaligned when the tower bolts have been tightened down. By that I mean the lower mounts aren't flush against the firewall (see picture below). The top of the mounting pad makes contact with the lower firewall but the bottom of the pad is lifted. If I were to drill the holes and fasten it like this I think it could warp the firewall..

My question is are "pads" or "spacers" required between the subframe tower and the firewall? (location pointed out in the picture above) I'm thinking they would help with the alignment but it doesn't mention anything of the sort in the allspeed instructions. What has been done out there?

When removing the standard subframe there were "pads" like this:

Im thinking something like the poly ones in the kit here:

You should have received solid spacers/washers that go under the tower bolts.

They're shown on page 6 of the manual here

I asked this as well,
no the is no need for a spacer between the bulkhead and top of the tower.
Any questions give allspeed a ring and they’ll happily answer them.

Yes I'm using those! I'm just concerned about the other side where the tower bolt inserts into the subframe (where the tower meets the firewall). Just because the stock mini subframe uses a spacer.

Right! Thanks for the info. I will give them a ring when I'm back home because I'm curious if you can run bushings there to help with vibrations. And I'm still thinking it will help align those bottom pads, were your lower mounts perfectly flush with the firewall?

No two Minis are exactly the same, the factory jigs ended up with 40 years worth of wear so the tolerances on later shells can be eye wateringly large. I suspect it will all pull up tight when you bolt it all down.

Right that does make sense. To sum things up here is what Rob from Allspeed told me:

"The Allspeed subframe is intended to be solid mounted, you just require the supplied large washer under the bolt head, nothing between the tower and bulkhead x member."

Yup as Oz said, I had this with a past build I did. The frame fitted once it was bolted up fine.

Solid mounted too, so I'd make sure you have the extra metal welded in as per manual where to bottom bolts up.
