My progress

[Bonzo]

The cooling fan was a front mounted unit & pushes the airflow into the rad .... All sits under the nosecone a real treat.

It was mouted to the original car via 4 strong wire/round bar arms .... Near as dam it, the same spacing as my new rad.
Sliced a few mm off & welded 4 flat tabs on them this allowed fitment to the mounting points on the new rad

The seat runners were found on a Renault Scenic .... Middle rear seat ( The small one ) only abot 400mm wide.
There are clips on the front hinges to allow easy seat removal ..... The tricky bit is getting to the runner fixings.
I prised the uphostery clips out & removed the lower seat squabs, access to the 6 allen bolts was then simple.
Just as well my local breaker is not too fussed about collateral dammage cos it fubared the seats

The only downside is, you'll need to find Two cars though as there is only One in each car .... Although to be honest, I didn't look at the runners of the other seats in the car, they too may be suitable !!

I'll take some pictures of the cooling fan & seat runners tomorrow mate
