Just a suggestion....check out LMC's radiators.....I've used them with no problems and they were reasonably priced, fitted without modification and keep my little 235 cool as a cucumber. I've found, over the years, that regardless of what brand you use, that distilled water and a 25/75 mix of coolant will keep things nice and cool and cut down on mineral buildup.
Their radiators are "British Unlimited" which probably means made in Hong Kong but at half the price of a Walker, it might be a viable alternative. I agree that the $200.00 aluminum imports are pretty skimpy and the LMC unit is brass.
Speaking of radiator shops....I've found that most down here don't even make repairs or modifications. Their tanks are empty, the floors are dry and the back room is full of aluminum radiators. Ain't progress great?
