Thanks for the welcome guys. Appreciate the info. Guess I'll be looking for a 55 frame. Bought the car and the frame has been tubbed and four link put on but I would like to have a back seat and it doesn't leave enough room. Thanks again.

 

welcome aboard fergie 55

yep look for a 55 frame :anim_25:

 

Welcome to the site. Post of some pics of that car....we love pics. Also, why not one seat in the back in the middle - tubbed and 4 link is sweet.

 

All GM's have a very weak side rail on their frames. Honestly I don't know if your car could handle the lack of support, in those areas.

 

hi fergie and welcome :hello:! good to have you here. have seen some frames on ebay that "look" pretty good :anim_25:

 

if the tub was done nicely, go to a interior shop and get a seat made. much easier. its not just the frame you have to change you know. rear axle, body etc

 

Is it a full tubbed car? If it was minitubbed then you can do like I did and install a 2 passenger seat out of a Chrysler Sebring vert. I minitubbed mine myself and that rear seat fits just right. Several other models you can find seats from.

Again, thanx for the welcomes and info. I don't have anyway of scanning any pictures at this time but I will get some on as soon as I can. The car is fully tubbed, it was built for racing. It is a super nice tub and 4 link set up. I think I will try to get an upholstery guy to look at it and see what will work with the set up. This is my first build so I am green and will be asking for alot of advice.

 

Welcome, Back to your original question a friend of mine bought a 55 hardtop that is on a mid 80's Impala frame. The previuos owner did a nice job on it and the advantage is that it has all the modern upgrades. He loves the ride and it sits low. I personly would prefer the Tub but yes it is being done. As stated you could probably find a good frame but if the Tub and 4 link was done right I think it would be less money and hassle to have a custom upholstery installed. Don't forget the "cool" factor of a Tubbed car. IMHO
