TR4/4A TR4 Door compatability

Hello everyone.. it's been a while since I've posted. I am trying to use 2 near perfect doors from my 1962 TR4 (CT6xxx) donor car on my "restoration" project 1963 TR4 (CT224xx). Looks like the Door Check Strap assemblies are different pre/post CT22344. Specifically the part attached on the door interferes with what receives it in the A Post. Is anyone aware of a solution for using the older door/checkstrap on the "newer" A post? or go the other way? I'd just hate to not use these doors. Thanks..
 
Hi,

I have the exact same issue with a pretty good passenger side door I bought and hope to use. (The orignal door is actually rust free and clean, but was shortened at there rear edge a little to "adjust" the gap, after a traffic accident many, many years ago.)

I will probably just weld a different set of brackets onto the door to mount the early style of check straps, since I have two complete, new sets of strap mechanisms on hand. Welding is the only solution I can see.

While I'll be making the door the same as was original on my car - i.e. compatible with the earlier style strap - I'm sure you could go the other way with it just as easily if you wished or that were more convenient. Originality concerns aside, I don't see much difference or advantage of one style stop strap over the other.

Perhaps one way to decide would be based on what parts you have on hand and would allow you to set it up with the minimum amount of additional parts to purchase. Or even let the prices of any parts you need to buy help you decide, if all other things are equal.

Even in terms of "originality', done reasonably well I wonder how many councours judges or other TR4 owners would ever spot the change? /ubbthreads/images/graemlins/wink.gif

I've got to make a related repair on the driver's door, too, which "lost" one of it's check strap mounting bracket tabs sometime before I bought the car in the 1970s. After I had to repair a crease in the door caused by opening it too wide, I learned yo live with a pair of homemade check straps - simply a couple pieces cut off an old, black seat belt and attached under the trim panels with a few sheet metal screws. It weren't all that pretty, but it worked.

I don't know of any other interchange issues. Heck, aside from trim, the door assembly remained pretty much the same all the way through TR6 production, except for some minor differences around the handle and the separate door lock, of course.

OK.. I think I have a plan. I am going to remove the Check Strap carrier/Guide from inside the A Posts and move them from the older TR to the newer so that the door will be compatible. The mounting looks similar except that the newer version 63 TR4 has the assembly riveted while the earlier version that I am trying to match is fastened with a screw on the outer part where the rivet is on the other car and two additional screws in the door jamb area. Will see how they come out.. The only downside I see is that the older checkstrap is much more $$$ than the newer version. I'll have to get new ones as the old ones are not useable. I think I prefer this approach than welding something on the door to make it work.. thanks
 
Well...it Looks like the assembly inside the A Post is spot welded in. On the 62 it is nicely bolted in with 3 Bolts and it comes out real easy. I like the older design better. So Alan, it looks like I will need to go your route and weld on new attachments to the Door Jamb to match the newer Check Strap style. I think i'll ponder this decision a little while though.. Thanks.
