Mort Posted April 24, 2012 Share Posted April 24, 2012 We have a R600 steel body which I believe was built around 1974. This seems to be about when the fiberglass. bodies appeared. When did the changeover happen and was there an overlap? Quote Link to comment https://www.bigmacktrucks.com/topic/24679-steel-to-fibreglass-body/ Share on other sites More sharing options...

yarnall Posted April 24, 2012 Share Posted April 24, 2012 Do you mean fiberglass flip hood verses butterfly steel hood? Quote Link to comment https://www.bigmacktrucks.com/topic/24679-steel-to-fibreglass-body/#findComment-115883 Share on other sites More sharing options...
41chevy Posted April 24, 2012 Share Posted April 24, 2012 Have a photo of the unit in question? R's were all steel cabs in the states as far as I've ever seen. Don't know about the Macks in OZ but I suspect they were the same as here. Like Yarnall mentions it could be a RD series nose you mean.

jeffbyrne Posted April 24, 2012 Share Posted April 24, 2012 Hi Mort, Firstly, this info only refers to trucks available in Australia. Are you refering to the cab or the hood? For the cab, they first appeared in mid 1973. I beleive there may have only been about 25 or so trucks built with this cab. There was no changeover date, the RP (Reinforced Plastics) cab was an option.The RP cab seemed to disappear around or just after the time the new steel cab was available in Australia, about mid 1975,When it comes to the hood/bonnet, both were available basically from the first release in 66/67. By about 1971/72 the steel butterfly hood was only seen on severe service trucks, and the fibreglass hood appeared to be the standard hood arrangement. Hope this helps Jeff. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/24679-steel-to-fibreglass-body/#findComment-115892 Share on other sites More sharing options...
Green Dash Posted April 24, 2012 Share Posted April 24, 2012 Great info. That's the first I've heard of the RP cab. Quote Jim Link to comment https://www.bigmacktrucks.com/topic/24679-steel-to-fibreglass-body/#findComment-115902 Share on other sites More sharing options...
Mort Posted April 25, 2012 Author Share Posted April 25, 2012 What an incredibly small world we live in at times. Jeff who 's info was so helpful lives in the same town as me in Australia! I'm sure he would know the Mack I'm referring to. I believe it was bought for road train work originally. This would explain the steel butterfly bonnet. These days it used on a low loader. It is a great old truck to drive with a wide load because it handles so well.Mort Quote Link to comment https://www.bigmacktrucks.com/topic/24679-steel-to-fibreglass-body/#findComment-115932 Share on other sites More sharing options...
