5Toyota

as far as the plug in goes the original flasher in the picture is the same plug as a 2 wire or can even use a low or high low sealed beam plug in I have done this .and yes that is the factory Toyota unit .

my 1987 dolphin model 400 has a front door . but a rear kitchen works ok for us . I do prefer the larger rear bath and ours does have that. I don't like front or side baths .

even tho my dolphin has 2 18 gallon waste tanks if wife and dauter are along for an extended stay remote camping black tank can get to full the solicion cant spell never could is I bought a 18 gallon thetford smart tote . you just hookup to dump valve . it has wheels. I carry it on a rear platform carrier bought that from harbor frt . works pretty good . thetford smart tote is the way to get xtra waste capicty, doubled my black tank. or can use for gray water .

I think winiabago used metal studs . the sunrader used a molded fiberglass body farless leak and rot trouble . most all the other makes used fiberglass sheet or metal sides . my dolphin is glass on sides and back and metal roof and top front of cab over .lot of wood in the walls . I live in a very dry climate so my 87 dolphin is still in reasonable ly decent shape . all of those using sheet construction can have a lot of rot after 30 years or so . forgot to say most used wood studding.

WME is spot on I have a 195 in my 87 xtra cab and my 87 dolphin the heater will roast you out . but as old as that unit of his if po have not kept up on antifreeze changes the heater core could be blocked internaly I had a 1978 that was like that and a dodge van.

same for us have 87 dolphin model 400 very happy and I see it has the great all 6 lug front and rear enjoy

Gurgle in the center vents . that is most likely the antifreze going through the heater core . I have that sound sometimes when you first turn on the heater control valve that opens the water valve to the heater core . are you shure the raditer is full .

I say orginal miles very nice clean top and bottom . the numbers in those old time odometers. will roll over and reset just as nice . I have done it 77 corona wagen I took it from 62000 to 240000. turned it over twice but I think yours has never been there .

the blower motor resister is held to the heater housing with 2 screws it gets hot if you run the heater fan on lower speeds any crap on that could make a stink maybe

I had a 1977 Toyota corona wagen 20 R with a electric pump in the tank .as far as I know the 1976 1977 and 1978 trucks celicas and coronas all 20r powered used the in tank pump .

the ones I sent today too Derek are still in busness

I don't recall the size of the fill plug on the side of the trans the rear axle is most likely 24mm.
