subframe for mk1

Will the mk1 only take the pre 76 front subframe, or is it possible to for a single bolt one?

Anything is possible - it's a Scamp.

Angle grinder - drill - welder - some steel

Job sorted.

When I got my MK3 it had an early subby with the four tower bolts, I changed it to the Single bolt mounting.

I asked about this for my Mk2. It was suggested that I could bolt on the missing rear sections of the subframe using parts cut from an early one. The single bolt tower mounts might be a bit more tricky depending on how the chassis is made. I've seen pictures of what someone has done with a MK2 and all they did was drill a big hole on the chassis box section and use the standard big bolt. I don't know how the MK1 chassis is made in the mount areas but it might be best to re-enforce the area a bit and you might need some spacers on the big single bolts. 

If you get really stuck I have an old Mk1 subframe I could cut some bits off. It isn't very straight though which could cause problems.


I have just looked at the pictures of your car on Facebook. Te box section used for the tower mounts looks a bit wider than the Mk2 so you should just be able to make the hole bigger that already there. What I was suggesting above depends on if you want to keep the subframe solidly mounted or want to use the later rubber mounts.

My mk2 was drilled for both single and twin bolt, used an old 2 bolt setup in the end mounted mine completely solid and never had issues and you get fantastic feedback....but the road noise/feed on bad tarmac is awful. .....my new mk1 frame is single bolt but Andrew has added more support to stop the box twisting than an original mk1 would have had.

Will you solid mount yours or use the standard rubber mounts ? I made up solid ones for my Mini as you could see the subframe moving when you rocked the steering.

poly mounts compromise between the two solid is brill on short/medium drives but after a long day can get v grating
