Hrllo folks, I'd like to know what rads people have used, and any comments as to whether they were successful or proved to over/undercool the engine. When I built my first Midge, the local scrapyard yielded a super rad from, I think, a Datsun of some description.  It worked perfectly.  Now I'm rebuilding another Midge with a dodgy rad.  It can be rebuilt, been quoted, £150. Bit steep, so looking at alternatives. As recommended Maxi  rads are almost as rare as rocking horse poo, and BMC 1300 rads don't have their bottom hoses in the ideal position, has anyone discovered a good solution?  Cheers all,  Mike.
